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.

Quite possibly. But which of the thousands on offer?

I would really like to invite a Microsoft Expert to my house, Here, Sit, Fix, PLEASE!!

I've tried the instructions of RobinsonSilvestre without any success.

Also deleted the app, then downloaded Sudoku again.

When I went to log into my account my user icon was already showing with my historical score.

I played a few games, then closed the game. When I re-opened Sudoku these games are not showed as played.

Is there a corrupted file on my PC ?

I have been in contact with 'Casual games Support' and received several emails suggesting i uninstall Xbox and Sudoku, shut down, wait, restart etc. No joy. Another suggestion was to find Local State and Temp state files, Zip the files and forward them via reply, if the files are too large use OneDrive.

I don't use OneDrive, preferring to store my stuff on my other machine and don't trust Privacy statements and policies.

The zipped files were huge, one was over 600Mb, I explained this and received another mail asking to go back to step one. All in a strange iteration of English which sometimes made it difficult to read.

The strange thing is uninstalling still leaves your setup and stats files on your computer, not their server. Huge data files taking up large spaces on hard bought disc's

I replied that i was fed up being messed about and i would uninstall and not play again,

Until there is news that the problem has been sorted.

This worked for me, thanks a lot.

Problem settled down for a few weeks after I uninstalled and reinstalled both Sudoku AND the x box app. As of the 13/03/24 it has started happening again but the previous fix did not work this time. New issue, sudoku seems to be having difficulties recognising my Wi-Fi connection and frequently tells me I am not connected to the internet. I even tried turning off my VPN but no joy.

This is incredibly frustrating because before this issue I had completed EVERY daily challenge from 2015 when they started to 2024 and now many of the months are showing as uncompleted. Please fix the problem and either restore progress or allow players to go back to the beginning and complete previous challenges again.

EDIT: Tried uninstalling only the Xbox app and resetting the sudoku app. Did not work and I am simply not tech savvy enough to be able to find, let alone confidently delete any file or folders as some people have sugested.
