Looks like I'm done with this app... got a new phone, and when I tried to log in on the new phone, it couldn't find my username, despite the fact that I am still able to log in and play on my old phone.

The only other option is to start from scratch on the new phone and transfer 8,000+ cards to my new account 9 at a time.

Might as well... been spending WAY too much actual money on this app lately.
