My armor reset and I can't play matchmaking

So I booted up the MCC today and noticed a couple things that seemed amiss. The first being that the season tier list was inaccessible. My first instinct was that the season was over or something. I’m Tier 100, so it didn’t concern me. But then I went into my armor customization and noticed that everything I’ve unlocked is now locked again. I currently still have my high ranked armor on, I just can’t change into anything else. Lastly, I can’t connect to any online games. Every time I try, I get a message that says “Contacting server to get latest matchmaking data. Please wait.”

I’m going to assume this is a glitch or connection error, but part of me is concerned that I’ve been wrongfully banned for something. But I haven’t received any email or notification telling me I’m banned. Can anyone shed light on this?

I just signed out and back into my Xbox account and now everything is back to normal. The tier list is accessible, all my armor is unlocked and I can connect to matchmaking. So I know for sure now that I haven’t been banned, but what was all that then?
