Apple Music "updating cloud music library" for weeks

I canceled my Apple Music subscription almost a month ago. When I restarted the Apple Music app on my Macbook Pro it immediately displayed a status in the lower left corner that it was "updating cloud music library" with a spinning wheel (i.e. indicating that it's still in progress). It's been showing this ever since. Any idea why this is taking so long? Also, I'm seeing a lot of discrepancies in my library. For example, music I am 100% sure I ripped from CDs and that I own won't play and I get an error that "apple music or match is needed". Should I expect this to be resolved once this cloud library update completes?
