Issue using Volumio as a UPnP Renderer

I’m constantly having to reboot my Pi 4 for the UPnP renderer to become visible. I use BubbleUPnP on occasion for Qobuz because it has the option to search by genre, which BTW is something Volumio should implement. Anybody know how I can fix this?

I’ve discovered that I actually don’t have to reboot everytime the renderer disappears. Toggling the UPnP on/off button in the Volumio setting brings it back up. While it feels this is a Volumio issue, at least I can stop constantly rebooting
