The worst thing is they don't do auto saved like bind w Google play. I was already far on the game and played for almost 3 weeks now. Then there's bug where it said connection unstable but I was be able to watch ad and buy online purchase. I can't claim my offline rewards or save to cloud. I tried to deleted it and when I downloaded it back I lost everything and had to start from scratch. This is the worst, why Google play won't save it and only rely on cloud??? This game is new so there bug
