Well, it's finally happening. Carbon for Twitter, long one of our favorite Android Twitter apps, is finally running up against the token limit Twitter implemented some time ago. Developer M.Saleh Esmaeili dropped the bad news on Google+, meaning the app won't be able to accept new users once the last token is used up.
That's the same issue just about every major third-party Twitter app has run into, including Falcon Pro and Tweet Lanes. Esmaeili says he won't muck about with API workarounds, so what we've got is what we've got. Esmaeili is looking ahead to his next projects, though.
Unfortunately, for Carbon, however, we all knew this was coming.
