Syncing for microsoft solitaire between win 8 and 10 not working. when will it be fixed?

Age of Empires: Castle Siege will keep the same save file between Windows 8 and Windows Phone 8 (and Windows 10, in time), so it is completely based in the cloud and you will be fine switching phones as long as you use the same Microsoft Account. I believe
IRB knows this from personal experience of switching phones.

As for other games, those will totally depend. Games like Microsoft Bingo / Solitaire / Mahjong / Minesweeper all sync your game data to the cloud and it transfers between Windows 8 and Windows Phone 8; Halo: Spartan Assault, for instance, will sync between
Windows 8, Windows Phone 8, Xbox One and Xbox 360. Other games will all vary.

If you are on windows 8 then this is why

Win 8 = Windows 8

WP = Windows Phone

• Microsoft Minesweeper (Win 8)
  
  Microsoft Taptiles (Win 8)
  
  Microsoft Mahjong (WP)
  
  Microsoft Minesweeper (WP)
  
  Microsoft Solitaire Collection (WP)
  
  Microsoft Sudoku (JP) (Win 8)
  
  Microsoft Treasure Hunt (Win 8)
  
  Microsoft Mahjong (Win 8)
  
  Microsoft Solitaire Collection (Win 8)
  
  Microsoft Jigsaw (Win 8)
  
  Microsoft Sudoku (Win 8)
  

These titles were delisted late last year but have still been playable for existing owners. That's set to end on April 5th, so you're on the clock now if you still have achievements left to mop up in any of these games. The Windows 10, MSN Games, iOS, and Android versions of these games remain unaffected, but not all of those support achievements. Since last we reported on this closure, Taptiles (Win 8) has been added to the list, while Microsoft Bingo will be closing on all platforms on the same day.

Saving Microsoft Solitaire Collection progress between Windows 10 and earlier versions

With the Windows 10 version of Microsoft Solitaire Collection, your progress is automatically saved to the cloud. This means you can sign in on any Windows 10 device and pick up right where you left off. The cloud even saves your progress on challenges and
achievements.

If you're also using a Windows 8 or 8.1 device, your progress is automatically saved to the cloud as well, and you can keep earning achievements and completing challenges between other Windows 8, 8.1, and Windows 10 devices.

Note Any achievements and challenges that you complete on your Windows 10 device will not be available on your Windows 8 or 8.1 devices. The Windows 10 version of Microsoft Solitaire Collection contains new features and challenges that aren't
available in previous versions of the game.

For example, if you play Microsoft Solitaire Collection on your Windows 8.1 device at work and complete all the daily challenges, you’ll find that these challenges are incomplete when you open Microsoft Solitaire Collection on your Windows 10 device at home.
The next day, when you return to your Windows 8.1 device, the challenges from the previous day will show as completed.

I get this error code when starting up jigsaw and mahjong on windows 10.

On the laptop with windows 8 they still work.

The other microsoft games like minesweep en solitaire and jackpot all work fine under 10 and 8.

I was having alot of problems with Windows 10...majong was ok, but card games wouldn't update, (all in microsoft solitaire collection). I finally repeated the challenges and was up to date, but had to uninstall Win 10. Win 8 (which came on my pc) is working
fine...but, no achievements show up for my challenges with card games. Majong is fine. Hope we get an answer...sure is aggravating!
