Mizu

I and my husband have the same model. (Android X1)
I can start a game. But my husband can't start a game.

There is capacity sufficiently both.
The version is 8.1.0.

My husband keeps waiting from July 11.
He feels sad very much. It's very regrettable that I can't play a game with him, either.
I want you to settle this problem fast.

I am suffering from the same problem.
I hope the problem is solved quickly.
My smartphone is Android.
