I have recently updated my Vero 4K+ and since I’m now on the Leia RC my UPnP is broken. I had a link saved in Favourites to my server running DLNA and now it’s no longer operational. Moreover, when trying to add a new source, uPnP is no longer even an option.
As a sanity check I checked and tried on my rPi3 running Kodi v17 still on my other TV and uPnP/DLNA is still working as it was.
