Songs Greyed Out In Apple Music

I recently switched to Apple Music and have many frustrations with the app. Mainly, songs I added to playlists that clearly still exist on Apple Music randomly will become greyed out and say “not available in your region”…but I can search the same song and play it. I saw another blog post and the suggestion was to delete the songs off my playlist and re-add them but this was 2yrs ago. I’m sure that would still work but surely Apple has a better solution for this now.
