problematic but love

I love this game, Im completely addicted to it but it has quite a few problems. First, the drop rate is terrible. second, I have many problems with it freezing and now I cant play it. It wont let me log in to the game (the username and password are correct) I deleted the app and downloaded it again and have tried at least seven times to log in, even on a different phone! Its great but needs fixing.
