Hi. I have a problem with signing in. I just signed out of Pokemon GO and when I tried to sign in again, it asked my Google account twice. Then, there was a black loading screen with a white loading icon for a tiny moment, and then the game restarted, doing the same thing again and again. I have no idea of what it could mean, but I think some of you could help me out. I have Nexus 5, Android 6.0.1 and the latest Pokemon GO update from Google Play. I have restarted my phone and reinstalled the game with no effect. I have also tried it on 4G network, so it shouldn't be caused by that.
