Microsoft Sudoku has once again lost my progress on daily challenges. Please advise when this issue will be fixed and my progress will be restored.

Thanks Jamie Zegar. I will keep your advice in mind.

This I consider procedure to mitigate the loss of results in MS Sudoku. I had a 15-day straight result and that was lost from one day to the other. This is not really acceptable and maybe the game should go back to the drawing board.

Also: After un-istallation the remaining results were destroyed as well.

I agree with you there is something very serious has gone wrong., because this was not an issue up to January 2024 .

My daily challenge progress partially disappears when I change time zones. If I want to go for the monthly challenge, I have to go back and replay all the games that appear as unplayed. Very frustrating. Microsoft, please fix this glitchy program.
