I have exactly the opposite problem: although I have deactivated autoplay in both the Qobuz app and the WiiM app, more songs are played automatically at the end of an album or playlist. However, this only happens when I use the Qobuz app via Chromecast.
My hardware: iPad and WiiM pro plus; latest firmware everywhere. That behaviour seems to be caused by the Chromecast connection.
Any ideas on this?
