Having the same problem. Tried the Remove Home Xbox thing, didn't work. Tried reenabling it, didn't work. Now i have 3 switches available. Played the trial when it launched and decided to get the game disk, and now i can't play a game i own. What a joke...
Edit1: also tried deleting the savefile + reserved space. When game started i stopped synch so to create a new save. No dice (pun intended). Game still thinks i'm a trial player. I had also tried reinstalling the game previously and hard resetting the console, etc. Nothing works.
I refuse to go through the hoops of microsoft's or ea's tech support. I don't have the time nor patience to deal with this kind of bs. If this isn't fixed by the weekend, or at least aknowledged by ea, i will just return my copy and go back to BF1.
Edit2: ok ate my words. I'm trying Xbox support. Will update with whatever comes of it.
Edit3: Spoke with a rep named Sweet. I told them all the troubleshooting i already done and thankfully they didn't ask me to do it all again. I referenced this thread and they told me they cancelled the trial on my account, but it should take a while to refresh, about an hour. As i ended the chat i tried it again just for kicks and the error persists. I'm off to sleep, will try again tomorrow when i'm back from work.
Edit4: just tested it this morning. Guess what? Yep, didn't work. Game still thinks i'm a trial player. What a load of bs. Rep said they cancelled the trial on my account.
Edit5: Contacted support again at work. This time they checked and confirmed that the trial had been canceled on my account but it still showed in my "entitlements". Not sure how that works. They asked me to wait for a few mins and came back confirming that it was now fully revoked. Then told me to delete EVERY profile from my Xbox and redownload then after clearing cache and mac adress. Will try all that once i get home from work and return with results.
