Screensaver - Fan art - two issues

I’ve 3 PMS. 1 Plex Cloud and two fully accessible from outside.
Issue 1:
OpenPHT in remote location will display fan art only from Plex Cloud PMS.
Issue 2 (or maybe that’s just the design):
On local network once screensaver kicks in will randomly choose a server and rotate fan arts, two other servers are omitted.
Now if server with few media has been chosen, there is not much to be seen. Could you please explain how it works? Could OpenPHT use fan arts from all servers?

Pushing up.

Going up…

And going up again.
