How to get cover art/info?

I changed my storage device to my NAS and even though my Movies folder shows all backdrops and movie info the TV shows don’t show anything even though there is .metathumb and .xml files but nothing shows.

The fact that TV shows don’t have backdrops is a bug.

But are you saying it also doesn’t show the coverart and information?

That’s correct, it doesn’t show any coverart.
