App problems with iPhone

I can no longer use the APP on my iPhone. It will not let me log in. I've resetting password thinking that was the problems and it's not. I deleted the APP and re-downloaded it. No luck.

What gives?

 

Ditto. Mine kinda works, but no messages or notifications. Also can't seem to back up to main menu and sometimes freezes up. Tried clearing cache. No help

 

Having the same problem.

Any other ideas? HELP!
