Log in glitch

I'm having problems logging into my account because it gets stuck in the last loading part(the small white fcmobile logo on the black screen), it just keeps loading repeatedly nonstop, I logged in with a guest account and it worked so I assume the glitch is with my account. I've tried the "delete and reinstall" but it's still gets stuck at the last part. I have very good connection by the way and please fix this quickly as I would love to continue playing as soon as possible.
