two computers showing different online sources in Rhythmbox
two computers, each running Ubuntu 18.04.1, each also running Rhythmbox 3.4.2, each with grilo media browser plugin installed. Each computer is hardwired to the same wireless router.
You can see in the two attached screenshots that the two instances on Rhythmbox show different "sources" #1 has a category called "shared", while #2 has a category called "online sources" and another (not visible in the screenshot) called "other sources".
Why are there two different lists? Why does #1 not show what #2 shows? How do I make #1 show everything #2 sees, and make the two be the same?
