Over the past month or so I've had trouble playing and logging into Pokemon Go via o2 cellular. I sign in and play fine on my home WiFi and can stay logged in indefinitely. Soon after switching to mobile data I'll get logged out and cannot log back in again. While I remain on mobile data, even on 4G with full signal strength, I can't login. As soon as I'm back on WiFi the game springs back to life.
I have no other Internet problems on mobile data and have tried restarting the phone and removing and reinstalling the Pokemon Go app to no avail. I've played for years on this handset, in this area, on o2 without previous trouble. Has anyone else noticed this problem?
