I was really happy to read about the cloud save functionality, hoping I would be able to play the game across my devices (lags really bad on my phone). However, it turned out that it doesn't really do anything. I've ticked the "Cloud" box near my vault in the vault list, and that was weeks ago (yes, it's still selected). It just doesn't do anything. I'm signed in to my Google account on both devices, and I always close the game by first going to the main menu and then exiting. The game itself works fine. Phone: GT-I9500
