I downgraded to 1.41.8.9834 and it’s still happening so maybe it is something on the Plex side not tied to the server? Or it started even further back than that version…
I also noticed on Roku it’ll flip to that unselected “default” background during loading when you hit play from Continue Watching as well. So there’s definitely a few references impacted by whatever is at the root of this bug.
Updated the title a bit to line up with just the general “loading wrong” bug.
