I have a bunch of homebrew spells. None of them are showing up as selectable for a new wizard character despite having the Homebrew toggle ON. 

also some feats appear to be just missing - a bunch of stuff too lengthy to list here. I’ll be patient and do something else while you work out the kinks. 

In Appendix B: Creature Stat Blocks, the phrasing of the Owl's Flyby trait and the Rat's Agile trait appears wrong. They read, respectively:

Flyby. The owl doesn’t provoke Opportunity Attack action when it flies out of an enemy’s reach.

Agile. The rat doesn’t provoke Opportunity Attack action when it moves out of an enemy’s reach.

In either case, the phrase "Opportunity Attack action" makes no sense; it should probably read either "Opportunity Attacks" or "Opportunity Attack Reactions".

I doubt they are going to fix this issue. It stems from the homebrew spells being assigned to the 2014 classes. The fix is to manually go in to each of your homebrew spells individually and add the relevant 2024 classes (listed under Core in the class selector dropdown). There is currently no fix at all if you are using someone else's published homebrew.

This character https://www.dndbeyond.com/characters/131365404/okn6VP can't choose origin ability score increases at all. When I was making the character, I swapped between 2024 cleric, 2014 cleric, and back to 2024 cleric, then gave it a custom background and a MotM species without fixed ability score increases. At some point in the process, every option to add the origin's ability score increases, either from the species, the background, or the failsafe option on the ability score tab, all vanished, and now those ability score adjustments can't be added. Recreating this sheet without swapping back and forth between the 2024 and 2014 versions of cleric did not result in the same problem, which leads me to believe it was the class swapping that broke this character.

Homebrew subclasses, Warlock Patron for example, not showing up as a selectable option for 2024 Warlock.

Same here, though I can't even select the Thirsting Blade invocation on most of my warlocks since the update.

When you say "Legacy warlock invocations aren't supported for the 2024 Warlock." Do you mean currently  or won't be or are not intended to be backwards compatible / used if not reprinted?

There seems to be a discrepency with 2014 hexblade's expanded spell list. The 2024 PHB lists many of the smites as no longer being concentration, but when selecting these as a hexblade (they do not show the legacy tag, they are the 2024 PHB version of the spells), they still show the concentration tag.

As a side note, it would be incredible if the hexblade could recieve some type of errata to the Hex Warrior subclass feature, replacing the double up of using you CHA modifier for attacks to something else. I understand this is unlikely however.

So many spells granted by a background or species appears twice -- or more! -- in the character sheet with minor discrepancies (legacy vs new?) or just full-on duplicates.

I've screenshotted several examples here:

the 2014 version of the haste spell has a [Tooltip not found] lol

Compiling a list of the issues that I've found on the characters I've made:

-Rangers and Paladins don't have a drop down menu to select a Fighting Style
-Hail of Thorns is still listed as Concentration
-On the Ranger character sheet, under Features and Traits, Weapon Mastery is incorrectly labeled as "Weapon Mastery - Paladin"
-Gloom Stalker and Fey Wanderer subclass spells are not automatically prepared. Instead, they are added as options to the general Ranger spell list
-Legacy Warlock Invocations are missing. I understand you all said they are unsupported, but are they intended to stay that way?
-Any word on what's going to happen to Pact of the Talisman?
-Pact of the Blade does not change the modifier to Charisma. I know you said this was unsupported, but Hex Warrior works as intended. So what gives?
-The Lessons from the First Ones Invocation does not provide a drop down menu to select an Origin Feat
-Artificers still can't select any of the 2024 revised spells and are stuck with the Legacy versions
-Paladin subclass spells are listed as at-will when they shouldn't be. I understand this is true for other subclasses as well
-The above also applies to Fey Touched spells
-Shadow Touched should have had Wrathful Smite as an option. It doesn't. This was briefly fixed but now I don't see it anymore
-Eldritch Knights currently have no limit on the number of spells they can have prepared at a given time
-Boon of Fortitude is not increasing the HP maximum by 40
-Boon of Skill is overriding all skills, which in turn eliminates any expertise the character may have acquired in previous levels
-Druid should have Create or Destroy Water in its spell list. It currently does not
-Two-Weapon Fighting Style does not add the modifier bonus when taken as an individual feat. It does add the bonus when taken through Fighting Initiate
-When selecting an old race with a new Background, the ASI's provided come from the race when they should come from the Background
-Dragonmark Races, as well as Ravnica and Strixhaven Backgrounds, only provide Legacy spells instead of the revised 2024 versions

Its an absolute joke you can't support the abilities YOU MADE. 

I mean, how do you apply a 10 minute, limited, + Charisma Modifier to attack rolls by clicking a check-mark on a static web-page?

Answer: You don't. At best you'd manually enter custom attack actions that emulate each weapon type in D&D into the subclass character sheet as selectable options to toggle on that allow you to use your Charisma modifier... but the player can also just click on the weapon and add their cha mod for the number of encounters the duration lasts for in 1 second like they did for the 2014 feature.

I appreciate your help. I guess that’s what I’ll have to do. That’s really annoying though.

Potentially dumb question: Should the 2024 Bard Jack of all Trade feature be applied to initiative?  I thought the answer was no, but I have a 2024 Bard Character that seems to be getting a Jack of all trades boost to initiative  Am I understanding the 2024 rules correctly?

Tiefling's Otherworldly Presence ability seems to add the Thaumaturgy can trip 4 times instead of just adding the one option that you select. 

Fey Wanderer spells are added to the spell list as options to be picked rather than being prepared automatically

What happened to the Brace maneuver? I have several fighters (my PCs and a couple PCs of other players in my groups) that use that manuever, but if we try to update to the new core rules Fighter, we'd have to give it up because it's no longer listed in the digital 2024 PH, or DND Beyond. So, what happened to it? I don't see why it would have been cut... It certainly wasn't overpowered, and it was one of about half the Battle Master maneuvers that was actually useful. Is there any reasoning or release about this decision, or was it just an oversight. 

While we're on the topic of Fighters, the Interception fighting style is missing from feats in DND Beyond. The only way to get it is to be a core rules Fighter and add it at level 3. There is no option to take it as a feat added later, or to any other class. 

Pact Weapon doesn't change the Hit or Damage to Charisma for any weapon. IT should be doing what it says below but it's not.  How could you of messed up something so simple from the 2014 book? 

Whenever you attack with the bonded weapon, you can use your Charisma modifier for the attack and damage rolls instead of using Strength or Dexterity; and you can cause the weapon to deal Necrotic, Psychic, or Radiant damage or its normal damage type.

Found another one... the Enhance Ability spell is still listed as requiring concentration. Pretty sure that was supposed to be fixed, when they lifted concentration from so many other passive buff spells. 

Rogue Soulknife Monk Multiclass:

• It looks like the Psychic Blades is not using the Monk martial dice for its damage even though it's a simple melee weapon and thus counts as a monk weapon.
• Psychic Blades are not adding the proficiency bonus to the hit roll.
