On Macbook, the play button does not play. Quit the app and reopen brings me to the same exact place, and the playing bar is still on. I cannot close it and start fresh. Everything else in the app functions, it just won't play. I was considering uninstall and reinstall, but I believe there should be a solution and you should be aware of this issue (I'm from drops team, you can reach out through slack / teams, wasn't sure who I should reach out to).
Describe your network setup
I don't think that's realted, as the app was working fine and I haven't changed setting
I don’t know how this relates to your equipment setup. I had an experience last week that was partially similar. Had a holiday genre queued and playing. Noticed the music had stopped, the queue appeared to be empty with no tracks showing but the listing top right showed 400 tracks in the queue with the remaining time hours showing.
Tried queuing something new with no responce, and hitting play had no response. Same was showing from all remote devices. I went to the NUC/ROCK Web UI and restarted the server software. Everything was fine after that, the queued tracks reappeared and hitting the play button started the music playing.
Can you display the queue? If so what does it show.
