I have occasionally noticed albums I have deleted on Apple Music still show in Sonos. The album title will show but the artwork has gone, as have the tracks within the album. They often disappear in time but often I have to add the album again in Apple Music then delete it again which often gets rid of it. However, I now have one stubborn empty album that won't disappear and this particular album no longer lists an artist - just the album title so when I try and add the album (in order to try and delete it) it shows up twice and deleting the re-added album just deletes that one and leaves the one I'm trying to get rid off. I have tried removing Apple Music and re-adding it, I have cleared my Apple Music library, I have rebooted my router, my Sonos speaker itself - before finally resetting the thing to factory settings - the thing is still there. As someone with OCD over such things does anyone have any other ideas?
