Ridiculous loop! I signed up to track packages and get more specific times. Tried to sign up on the website, fail...finally got it on the website. Downloaded the app thinking it would be easier, kept asking me to sign up for details. I sign up AGAIN and it says user account exists. Log out and back in with signed up account. Once I log into account and go to track package in detail, it prompts me to sign up instead of re organizing I'm already logged in and signed up. So frustrating.
