I have a bug, when I am beating a level, I don't get moved automatically to the next level and have the "play" panel for the next level to pop up automatically. This is a bit annoying since I have to manually click the next level to play. Restarting the app is "fixing" the position but it occurs once again upon beating a level. I didn't try to re-install since I don't want to loose all my bosters…
Also I can click Map / Events / Friends or Shop but nothing happens (I also have to restart the app each times)
