Help ever since I restored my Iphone 5 verizon from itunes my twitter account loads everything but when I look at my feed I get error 400 and haven't seen a tweet since the new phone?
Same thing happened to me. Delete the app and download it again. That fixed it for me.
Had this quite a bit yesterday also.
Goto Settings>Twitter>Select your account
Update/change password.
I had to do it twice.
I did that also, but didnt matter had my password wrong and had forgot about Twitter in Settings.Yep thats all you need to do. No need to delete and re-install the app.
