The game was working well (There was always bugs anyways) until the update. I can't raid or catch any pokemon. I can't put pokemon in gyms. I literally can only battle, all because of error 11 (GPS signal not found). I did research on the error and did everything the sites said and the same error happened. It worked at my school once but that was the last time it worked. I think it might be the service in my area or my phone just malfunctioning, but please look into this problem if you can.
