Device not showing up in Plex for Android app to cast to

I have a bunch of raspberry pis and a Samsung Blu-ray all with Plex. My Plex app on my phone can cast to the raspberry pis but has stopped working on the Samsung Blu-ray. It shows up in Plex web though. I’m hoping for any ideas on how to fix this?? I think it might have happened after the most recent Plex server update.

Is the the Samsung Smart Hub app? The Android app should read the same info the Web app does. I’m assuming you have restarted everything. what version is samsung app at

Yeah it’s the Samsung Smart hub. The Samsung app is 2.006 which it seems to think of is the latest. And yeah I’ve tried restarting. It seems really strange that it shows up on Plex web and not Plex for Android though. Any ideas?
