Halo CE and 2 Locked Off

2 days ago, my MCC on PC said that I didn’t have acces to Reach, CE, or 2, campaign or multiplayer. I checked to see if my game pass subscription was paid, and it was. I uninstalled MCC and just today reinstalled it. Now it says I have access to Reach, but not CE or 2. The installation screen shows a blue lock on CE and 2 but not Reach, even though I should have access to them all. Anyone else having this issue?

Yes, I have had issues after completing Reach; CE, 2 and 3 are showing as locked and trying to play them takes me to a windows store login screen which states that something went wrong their end, try waiting a while and try again! I have tried many many supposed fixes without success and have lost count of the number of times I have removed and re-installed the game. Very very frustrating.
