Logging in

The game is great but it wont let me log in to my profile at all!! I wait for atleast 5-10 minutes waiting for it to load and it doesnt! And its not because my phone is and older version I have an iPhone 6s and it does not load! Game is just not fun if you cant log in at all. Please fix this and yes their is lots of bugs in this game and please fix this logging in problem!
