Delighted to see AirPlay 2 support annouced. However, bubble well and truely burst by twitter support confirming it only works on newest devices - the play5 gen 2, and play base.
Can this be explained further, is it :
(i) Only new devices will support AirPlay 2. So if I have 6 Sonos speakers, 2 of which are play5:gen2, only those 2 will show as airplay speakers?
(ii) You need at least one compatible device in your ecosystem, which acts as a bridge for older devices. So in scenario above, as at least one play5:gen2 is in the mix, all speakers are available.
I am crossing everything that it is (ii)... or there will be a lot of very unhappy people!
