The control app thread

[simbun]

I think it was @simoncn that said the Synology media center didn't exhibit similar behaviour because it broadcasts more frequently than MinimServer, so I went looking for an equivalent setting in BubbleUPnP.
In theory, if this works and you're having the same problem with MinimServer you may be able to proxy that too.
This change will marginally increase network traffic, so it might be worth playing with the interval.

I did try the Lumin app to test this change but I couldn't get it to fail in the first instance, although I am on Android.
I set up a multi-hour queue and set it off, putting the app in the background and coming back every 90 minutes or so, but it still showed the correct screen, queue and track position.
