When I open a new game, it appear the following. 
The operation was canceled. at Amplitude.Mercury.Game.Game+<DoStart>d__4.MoveNext () [0x00157] in <26d5eabde6884af4a4c6afa86ba71021>:0 at Amplitude.Coroutine.Run () [0x00019] in <8998cd17966f44ffa18154eac980fd39>:0 

Before that I cannot save a game.
