Premove instead of a move

Today I played 15-20 games and on two occasions it was my turn to make a move. Instead of allowing me to move the app was showing it as a premove. My time was ticking down. In the first instance, I got out of it by simply waiting. Then I was briefly allowed to move only to be told that the other player had left and I can claim the victory. In the second case the game was shorter and I had to wait for time to run out. The weird thing was also wrong check notification.

This usually happens if you lost connection to the server for a while, AFAIK.
