Thanks Sonos for making this super confusing!
im going to ask my specific question since there is so much info out there on different situations and I can’t be clear as to what the right answer is unless I create my own.
Is this possible: I would like to add an aftermarket older version Jen one play five speakers to play in my kitchen, same music new room. Already upgraded my current system to the new app app S2. I am seeing conflicting info on the Internet as to whether or not I can now play my new system with the old system.it seems as though I can, but I need to downgrade my app to the S1. I am hearing that this is not possible please confirm and let me know what is possible.
