At least with the latest app update the queue can be edited again. However, I now get an error “cannot add to queue” - this happens after adding two (!) albums to the queue, from a music library. There are 24 items in the queue, and I can’t add more. After a few tracks are played, then it seems to allow another album to be added, but only one.
Can someone from Sonos comment - is this a “feature” of the new app, or is it yet another bug? Either way, it needs to be fixed, yet more incompetence in a basic feature.
