I was level 57, I loved this game, had no issues at all for months. I did a software update on my device and when I went back to finish the mastering all items job, all my stuff was gone. Which makes no sense. It never let me sign in to my Google account either, which makes it worse. So, after a few tears, I tried to start again but now, everytime I leave the app, the whole thing is wiped. I can no longer make progress. I am very upset and feel as though I have wasted my time. Please fix this.
