Suddenly, I only have maybe 8 feats available to choose from in the creator. Did they nerf them?

If I have to pay more money, I'm fed up. I've already paid for a ton of stuff and I have a subscription. I had the whole list of traits a few days ago.

Considering we get no virtual tabletop with our subscription, which means we have to double spend, I'm quickly losing faith in this website.;

Which feats disappeared? Were they feats from the PHB, or were they the playtest UA feats?

If they were PHB, and you bought that here, follow this link and if it offers to let you “resync” your entitlements, do that: https://www.dndbeyond.com/account/marketplace

If they were the UA feats, those have all been archived and are now only available in their updated form here: https://www.dndbeyond.com/marketplace/sourcebooks/tashas-cauldron-of-everything Simply scroll down to see the individual purchase options.

Not sure why, but I recently made a Blue Ancestry Dragonborn Artificer with the Origin Ability Score Increase option selected. When I try to chose infusions, the list is completely empty for all 4 options at both lv 2 and 5. "- Choose a Lv 2 Option -" is the only thing that shows up in the list.

That is a completely different issue from the OP. The thread you want is here: https://www.dndbeyond.com/forums/d-d-beyond-general/bugs-support/88368-artificer-infusions-in-character-builder

So the new book took away stuff I already had. Forget this. I will just start buying everything on Roll20.

The UA (Unearthed Arcana) feats were public playtest (and free). They have since been officially released in the book - therefore the UA feats have been archived because they are not playtest any more. This isn't a DNDBeyond decision - it's a Wizards of the Coast decision - and the exact same thing will happen on Roll20.
So if you decide to leave DNDBeyond for this particular reason - it's misguided.
