I have two Sonos Moves (not stereo pair). Originally named PatioSonos and GarageSonos.
After some issues (notably with Apple Music). I decided to start again; I reset both Moves, reset the apps and went through the transfer ownership routine.
Then set up again this time with names Patio and Garage.
One or other Sonos app (using iPad and Mac) changes BOTH names to PatioSonos. Changing them to Patio and Garage again only lasts a few minutes.
Changing one would be annoying but livable with; changing both is not just poor QA on the Sonos software but makes using awkward (as a minimum, I have to test play to determine which is which!).
Any ideas/suggestions to really reset to factory settings appreciated...
