If my modem reboots, I lose my place in my queues, even if Sonos is not currently playing. I’ve tried closing the app on my desktop when not in use, and still lose my place. Tonight I just paused my music, and lost my place. OS X Big Sur, Sonos Play 1 - 3 paired sets, 2 singles. Places are lost on singles, pairs, and playlists where multiple sets are connected.
