Siri can't find songs in my library
When I first got my HomePod a few months ago, everything worked fine. No Apple Music, but I do have iTunes match. Recently, I've noticed that most (maybe all) requests to play a specific song result with Siri telling me that she can't find that song in my library. But if I ask Siri to play the album that contains that song, she plays it no problem. It also works if I ask Siri to play specific playlists.
Any idea what's going on here? I've restarted the HomePod, which did not fix the problem.
