iPad Air (1st Gen)
I'm also having recharge issues where, during the tutorial, if I have Ameiko cast Aid on Orik for any check, it won't let her attempt a recharge. Was able to repro over multiple tutorial runs.
When creating my account in-game, my fields would copy from what I had in the previous value (from Username to Email, email to password, password to confirm password). This happened on tap to change between fields, and if I went back to modify a field, it would copy again (so when I went back from blanking my password field to fix an error in my email, it blanked out my e-mail.)
I previously also had store issues, but that appeared to have been tied with me logging with with Facebook (Known issue). Works fine with a regular account.
