not going to clickbait you, but like and subscribe anyway!
This has been going on for months, and I don't remember it ever happening in the past. Any time you go from cell to wifi or oppo the game gives you a Connection Lost error, then forces a restart and wipes your attempt/team etc, so you will lose out on an arena attempt, a gac squad (with it counting as an attack), a tw attempt (also still counting the attack) etc etc. I guess there's enough connection to wipe your attempt but not enough to just play the attempt? This was not a problem until a few months ago iirc. Will anything be done about this? I used to be able to walk the dog around the block and the game would just switch back and forth from wifi to cellular, like any normal game or website or w/e would do, but something clearly changed. imo
Maybe End Game isn't for you
