As the title suggests, the official twitter app keeps crashing when I try to open it.

I've tried restarting the app, a cold reboot, deleting and reinstalling, but nothing works.

I recently added a second account, and when trying to reopen it hasn't worked since. I can't see how this would be a problem?

Any ideas? Thanks.

PS - I'm running an iPad 4, 3G, 64 gb. And I close down a lot of things in the multitask bar.

Hm?

Try going to Settings > FaceBook and sign out of both accounts. Re-download the app. Add each account back one at a time to see if/when it breaks.

I have no idea if this will work. It's just what I'd try next if I were having the problem you are describing.
