Just upgraded the controller on MacOS today (now version 16.2, S2, 79052294, 135275309)
Music Library disappeared and trying to re-add it gives
“Unable to add the shared folder “//MACBOOKPROB277/Music” to your Music Library (1002).
This is after turning on File Sharing and giving read/write to Everyone, otherwise it would be stuck on “permissions”.
My setup was working perfectly before today without file sharing turned on.
