but
@mccririck isn't using a WiiM mini, he's using a Chromecast Audio which also doesn't hold the queue without BubbleUPnP server.
In addition, the browsing experience is horrible through the WiiM app. I don't know what music server you're using, but MinimServer and BubbleUPnP are in a different league to the WiiM app, I could never downgrade - which is why WiiM not working with MinimServer (via a 3rd party controller) is a deal breaker for me. I've only had it a week and have reported the issue so we'll see how that goes.
