I messed up my first attempt to login. After that, my original invite code no longer worked. I requested several new invite codes, and none of them work either. I am locked out for good. Seems like the developers for this app spent zero time testing the login functionality. Tisk, tisk.
More: I used my invite code, got to the login screen, them got interrupted before creating a password (closed the app). Now I can’t use a new code, and the forgot password feature doesn’t work, probably because I never completed setting up my account. Non-standard login design IMO. And why delete the invite code? Doesn’t make sense to me.
