Plex pushing all playback data except cover image when casting on a Google cast device.

[maxi1134]

The problem

It seems like the Plex integration and the Cast integration are only working at 98%. In the sense that the cover image is never pushed to the cast player, while the rest of the data is. (Title, duration and so on )

What version of Home Assistant Core has the issue?

core-2024.3.0

I am currently using this to extract the image with a third party integration called "template media player"

Anything in the logs that might be useful for us?
