This kind of has us scrambling a bit, actually. Not because we'd have to pay per se, but rather we've been using their API for so long on our website (and def still on v1.1) that now when we check the developer site it just funnels to a "Sign up" and no longer shows us our existing/old apps, so we cannot find/figure out which account was linked to our production credentials (and that's really on us for not staying on top of which account that was).

But even if we login to the account that holds our test API credentials (maintained entirely separately for security reasons), it doesn't show our app at all, which is annoying AF. Add to all that, when we try to login to one of our accounts to see if that is the one linked to our credentials, it forces 2FA via email which normally would be fine, but: Their emails aren't even working.

Twitter feels so broken right now and barely over a week's notice is a huge PITA when our dev team is already pretty slammed as it is.
