Hi @blunt81st
Solution was to remove all my devices from the system and then re-register all items again, this time including the Sub
Could not do it on my Google Pixel 6 phone - constant errors, but managed on my Galaxy S22.
Wow. OK. Well, I’m glad you got it fixed, but I guarantee you there would have been an easier way.
We don’t recommend factory resetting Sonos devices unless specifically requested to do so by our technical support team, or if you are selling the item. Resetting all your Sonos devices will result in all accounts, favourites and playlists being removed.
