All music in my library, except the ones from Apple Music subscription, and music downloaded, cannot be played on my iOS devices(iPhone, iPad and Apple TV). An error appears "the requested URL was not found on this server". Spent close to two hours on a chat with an Apple tech. We troubleshoot everything that they could think of. And it's not my internet or wifi connection, all my music can be played on my MacBook. I'm sure there must be a glitch that will fix itself...so far I haven't had any problems with Apple Music in 2021. But it had to start at some point; every year, at least once or twice there's an issue. Anyone with the same same problem?
