Description of Issue

Since a little while the search function does not work at all.
I cannot exactly tell when this happened. Everything worked fine up to that point.
I was prompted for a system update, which I ignored because I was listening. I never was prompted thereafter. Did it update without my permission? Anyway, I suspect it has to do with an update, since everything worked nicely before.
In addition I have the following issues:
Playlists / queues stop playing almost after every songs end. I have to manually skip or start next title.
When looking for an available software update, I hit “Find Roon OS” under “Setup” and the system just shows “Searching for Roon OS Core” and does not find it.

The not functioning Search and the discontinuation of replay when playing queues is very annoying!
Looking forward to quick advice or a software update / fix.
