Was finally going well for a few days, and even a 30 second ad seemed ok with keeping the completed games up to date.
Then today, I played after a 30 second ad, and nothing was saved. I thought after this long, this would have been fixed, but i don't know why I thought microsoft could (or would) bother fixing this ongoing issue.
This forum is even on the Microsoft site, yet it still isn't fixed, or been addressed with any positive attempts at resolving this.. They must be too interested in not giving a ****.
