When I start the app, I'm given no option to re-enter a username. I entered the wrong identifier and now it is stuck in my phone, even after uninstalling and reinstalling the app.
I have tried deleting the account but still the wrong identifier is there.
All I can do is copy the identifier to the keyboard and that's it.
I'm getting ready to uninstall for good.
Have you tried to clear app data via settings-> applications?
