I've downloaded the app and even registered an account once, recently before. It keeps kicking me out. Or says that my UN/PW is wrong. I've tried doing a PW reset, but said my account doesn't exist. So I tried registering again, but when I completed the process, it throws me out. So I lastly tried to look up my flight via my last name and confirmation number, but it it keeps 'thinking' and gets no where. Am I missing something? I even email mobile support & got a undeliverable kickback message.
