Something's wrong with Twitter.
I made the move and switched names. But little did I know that Twitter users are having problems switching account settings, usernames in particular.
Now I can only sign in with my email, but when I do the username reverts to the old one. If I click “home” to post an update it takes me to the new account with the old username.
This also means I can’t use Tweetdeck (desktop), or UberTwitter (mobile) – big problem. On top of that, when I sign in it reverts my changes (see bellow).
