I can not watched archived MLB games anymore on my 4K Apple TV (Gen 1)

I have a subscription to MLB TV, which I use through the app on my Apple TV. I typically watch archived games because I'm subject to blackout restrictions for all live games in my market.

Up until a few days ago, everything was working fine. However, suddenly the icon for the home team broadcast, specifically the YES Network in my case, has disappeared, leaving just a black space where it used to be. I've tried several things but haven't been able to resolve the issue. Any suggestions or advice on how to fix this would be greatly appreciated!
