Hi, I'm Bernard. I'm happy to help!
Based on the information you provided and the subscription you mentioned, it appears that this may be a temporary backend issue affecting Microsoft Solitaire. I recommend waiting 24–48 hours and then checking the game again to see if the issue has been resolved.
In the meantime, you can also submit feedback to the developers so they can further investigate the issue:
