Not sure if this is the best forum spot to ask and get good answers.
Sorry my first day as a ARC owner, or any Sonos product.
Trying to setup and use my new ARC.
My apple XS max is telling me I must update to use the ARC.
Thinking it would be better to use with a old Sonos operating system.
Is there a way to go back to old firmware?
All helpful tips are welcome!
Thank you!
