It is not currently possible to attune to a wearable item that is not currently worn, and if an attuned item is un-worn the attunement is removed from the character sheet.

This does not match with the core rules, as it's not required that an item be continually worn to maintain attunement;  some abilities may still function for an attuned item when the item is worn/equipped or not, so it is important to be able to track the attunement when not worn.

Well, any wearable item, really.  You can only attune to 3 items at a time, and removing attunement is not at-will nor instantaneous - a PC must spend a short rest focusing to remove attunement, spend more than 24 hours away over 100 feet away, no longer meet attunement criteria, or die.

So removing the attunement just because the item is no longer worn/equipped is incorrectly altering the attunement list, requiring players to track attunement separately so it can be re-instated when the item is re-equipped (particularly since attunement is not instantaneous).

Take for example a Fighter using a sword with a shield (which requires attunement), who decides to use his two-handed weapon.  The Fighter must un-wear the shield, as it will otherwise be granting AC bonus and skill Disadvantages that should not apply.  Doing so will remove the shield from the attunement list.  Or look at Shield of Missile Attraction, where the curse continues while attuned, even if not equipped.

Alternatively, what if a player un-wears (as opposed to 'remove' since that actually removes the item from the sheet) their (attuned) armor to attend a royal gala for the evening?  They're still attuned when they return to it that night.

Although in my case it was a Homebrew item I made for a shield from Ghosts of Dragonspear Castle, the Apple Tree shield that once bear day the bearer can reach into the shield and pull out an apple, which acts as a Potion of Healing if consumed within one hour.  A character who does not normally use shields has attuned to it for access to the daily power.

 Then just keep using it. You don't have to rely on Dndbeyond sheet to keep track of everything(e.g. unwielding your dagger every time you put it in your pack)

For campaigns in which the DM prefers an accurate account of what locations in a PC’s Kit each piece of equipment is at any given time, keeping items as always “worn/wielded” is less than ideal.

I for one agree with the OP.. in fact, I thought the exact same thing  they announced this particular “improvement” in the Bug Bash. In retrospect, I wish I had left a comment to that effect.

But that is the point of dndbeyond, to do all that for you. Besides, the shield example would have you either mentally subtract its bonus, or give yourself a penalty to AC as a workaround.

Besides, the sheet is supposed to work according to the rules, limitations on implementation aside.

Why are you unequipping items every time? Like your example of switching to a two handed weapon from sword and shield. Just leave everything equipped.

 If you want to unequip your weapons every time you switch them it's up to you. Dndbeyond is a great site to keep track of everything, but you shouldn't be dependent on it, it's much easier to keep your weapons equipped so you can spend more time roleplaying instead of clicking buttons on dndbeyond.

I mean, you should keep track of spell slots, inventory, features from it(Shield unequipping can be tracked on dndbeyond too), but unequipping weapons every time you don't use them is a bad idea.

Are you going to delete all your inventory if the DM says, "You are in a prison cell with your packs taken by a guard."?

So what about people using the digital character sheet and built in dice rolling? (Or Beyond20 - and before you say "but that's not supported!" this affects the built in dice roller just as much).

What if it's swapping between two items that affect stats, and you can't use both at the same time?  Say swapping between a belt of giant strength and another belt.  Or removing an item that gives Disadvantage?  Wearing some items directly affects the function of other parts of the character sheet, and a character may be able to swap between items.

In this case it's a shield the character wants to benefit from the power of (which only requires attunement but not be worn), but is not actually wearing due to lack of proficiency.  So when equipped the character has disadvantage on multiple checks.

The character sheet's function does not match the game behavior in this case; the item isn't being removed from the sheet, it's merely being un-equipped.

You seem pretty determined to defend what is clearly incorrect behavior... Not everyone uses it the same way you do, and it's unreasonable to expect people to do so.  It is reasonable to report bugs and expect them to fixed.

Because the shield affects AC and in this case also causes Disadvantage on many things for the character (due to lack of Proficiency), the character wants to remain attuned (to use a power), but not actually use the shield most of the time.  This is a legitimate use case.

"Mask of the Crimson Thief" - Requires attunement. Grants ADV to stealth and DIS to Persuasion.

If I want to roll Persuasion without DIS, or for that matter, with ADV, I HAVE to take off the mask, which unticks attunement in Beyond, even though my character is still attuned per RAW.
