Hey there, hoping someone can help me out with this question. I have two Sonos groups in my house, one stereo pair of Ones (right and left), and another surround group (Beam + two surround Ones - R and L + sub).  Anyone know if there is a convention as to which Sonos speaker should/does become the group coordinator (for example, when both the stereo pair and surround groups are grouped together into one overall group)? It seems most likely that in the case of the surround group, the Beam would become the coordinator (though I can’t find any documentation to confirm this). The case of the stereo pair is less intuitive though - which one becomes coordinator, the left or the right? Is it randomly determined, determined based on alphabetical/numerical order of the device UDN, or always the R or L by default? Thanks in advance!
