Microsoft Solitaire Collection: Xbox Live Error Code 121010 on iPad and iPhone

After paying for the Premium version I began receiving the error code 121010 regarding not being able to save game data in cloud. This was happening on both devices. As many others I seached the internet for a solution. But no remedy for my situation.

It appears that I solved it in the following simple way on both iPhone and iPad:

1. Log out of the game

2. Delete the app (and data) but keep subscription

3. Restart device

4. Reinstall app

5. Log on Xbox live

Best regards,

Matt
