I'm getting an API error on both the the app or the website when I attempt to add the Spell Sniper(Bard, Sorcerer, Warlock) Feat to my one D&D playtest human in my versatile or my background Feat dropdown option. Both me and My DM have recieved this error.

Error code text:

Whoops! We rolled a 1 on our API check. We're heading into town to visit the blacksmith for repairs.  Try again after a Short Rest.  Error Code df8f44a57d124f14bb7b525db1da3b9d Version @dndbeyond/character-app@1.20.6

1DD is not currently supported on DDB. I’m not entirely sure what you mean by “in my versatile or my background Feat dropdown option” since backgrounds cannot currently add feats and I don’t know what you mean by “versatile” in this context. However, feats can be added directly to your character sheet itself in the “Features & Traits” tab under “Feats,” simply by clicking/tapping “Manage Feats.”

I hope that helps.

I'm having the same problem, with my warlock. I even created a new character and tried to add the spell sniper feat, but it's missing from the list, even if I turn off prerequisites, it's simply not an option.  

The spell sniper feat is not free content and must be unlocked through purchase. Have you purchased it or thePHB?

In your campaign that you are currently in (If that content is being shared with you) make sure content sharing is turned on for you. It should then show up

Content sharing is on, and we have a host of books in the pile, all the standard books PHB, DMG, Tasha's etc.

OK, I just figured it out,  I bought the PHB, and suddenly I have a ton more feats including spell sniper to pick from.  So it looks like you have to own the content to get the whole list of options.

Correct, as I explained in my previous post.

ancient, but same issue - ddb says feat already exists, but does not, and when trying to add, errors out
