"[...] far more prone to incompatibilities with users WiFi configurations [...]" <- Exactly this! With my Unifi gear, all the configurations that had to be tried out and tested were driving me crazy. From Multicast Filtering (IGMP Snooping), Multicast Enhancment (IGMPv3), Broadcast Contols, mDNS to even the fucking Spanning Tree Protocol on the Switches (STP vs RSTP). How is this plug and play? How are other users even getting anything to work when it comes to multi room and speakers being on seperate APs?!
