Finally have 10 mins spare to make an update.
I worked it out.
I noticed I also didn’t have multi room sync available.
Myvolumio was not enabled on the correct players. For some reason I have a couple of instances of the same players in the available player list and I had enabled a dead link.
A game of suck it and see soon found out which ones actually worked. Now all the functions started working.
Still not sure why I have apparently redundant players with the same name but at the moment I don’t care. They are not doing any harm.
Buonasera infinity play back non si attiva più solozioni?
