Worst app ever! Worked when I first opened my account 2 weeks ago. Then I started getting 'service temp unavailable' more and more, and now I haven't been able to sign into the app at all for 2 days now. Customer service hung up on me. Twitter help was no help. I've tried everything - clearing data & cache, uninstall/reinstall, turned my phone off for 1/2 an hour then reinstalled, changed my password, etc. Still can't get in. I have never had such a problem with any app before in my life!
