Well, I did not use my Raspi 4 in 3 days. So no changes whatsoever.
But during my previous session I saved the default queue to a playlist using moOde's web frontend.
Today, suddenly it seems to work as expected.
BubbleUpnp loaded the previously used queue. I was really surprised.
I performed a reboot, all o.k.
I added something to the queue, reboot, all o.k.
I performed a power cycle again (I know... just to be sure) and again, all o.k.
I am sorry if I caused any inconvenience.
I will report back here if anything changes.
