I was recharging my portals and boom: someone turns off the lights.
Reboot the game, it happens occasionally especially with low connectivity/low speed.
Yes, reboot the game. Close the game and then open it again.
It shoudnt do this at all to be honest but early in my journey i realised i was using over 10gb a month on Mobile Data and the only thought i could put it down to was the map was downloading itself fresh each time i went out to play rather than downloading a local area map once and only updating if changes/new areas were detected/unlocked...weird thing was going over to pogo i never hit my limit once
Its sonething in the background causing this im sure...at least you can access the on screen menus where i cant.
Nowadays the Black Screen Is My Friend 😆😜😁
