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.

There is a simple workaround to synchronize the save in cloud:

1. Do your daily challenge on pc, click done when finished.
2. Open microsoft sudoku on a device (android or ios) with same login and begin a challenge (then exit)
3. Click on your Level / Login name in Microsoft Sudoku on the PC (it will open the Xbox app) and when you return to microsoft sudoku it will say it's not synchronized and will do the trick.

"Simple" workaround?

Well, the simpler i've found at least

its fixed

Works for me, thanks!!!

I've been struggling with this problem since late January or early February.

Most of the solutions proposed worked, but only the first time.

I installed the game on Android, and in more than 3 months I never had any problems. Also, playing on a Windows 10 PC without updates up to date, I have no problems either.

I thought maybe it would be a random problem, but no. I think the error depends on which server the game connects to. How do I find out? Because of the advertisements that appear before playing.

Whenever I see advertisements of this style (even if they are different games) the progress is not saved.

And whenever these types of ads appear, the progress is saved correctly.

I tested this hypothesis for more than 2 months, and it always happened as expected.

Also, if I started the game, the GOOD ads appeared, played several challenges, then for a matter of time the ads appeared again, but in this case the BAD ones, played more challenges, then closed the game, and when I came back, only the progress up to the BAD ads had been saved. .
