Siri refuses to play My Music from My Library.

Unless you have a subscription to either Apple Music or iTunes Match Siri on HomePod is limited to calling up your unhidden purchase history from the iTunes Store. You can AirPlay from your computer or iOS device to hear other content, playlists, etc.

Extremely annoying trying to avoid the auto-play of music I don't listen to.

So when I can get my AT&T Fiber to actually work, I'm planning on trying IFTTT for customization.

I haven't seen anywhere that it helps with HomePod but I'm willing to research try it.
