Apple Music
I have been strugglng for months with the Apple Music issue of my HomePod replying to a request with "Sorry there was a problem with Apple Music". This in every case applied to albums or playlists I had previous been able to stream via HomePod. Normally with Apple products, I can go to these support boards and figure things out myself but this has dragged on and on and on. I do not filter explicit songs nor does shutting things on and off work, nor does software upgrades.
I believe I have finally found the solution. Cancel Apple Music, put my HomePod on the shelf where I store old products I do not use any longer and buy a a different home speaker and music streaming service.
