Last night I found out the hard way that Plex can be a bit dodgy on Tizen based TVs.
The server was streaming all my movies files correctly but the Tizen client was failing and having weird errors. I was getting this error about enabling verbose logging

which was very frustrating and no real solution seemed possible even with AIs help.
Then the stream just started randomly working after trying different settings for like 45 minutes. Not really sure what I changed but it worked so I guess that's good?
I might also install Emby server and the client app on my TV as a backup just in case for these situations. I assume the library should just work the same. I wanted to install Jellyfin but sadly their Tizen client isn't available in the app store.
I also realised that on macOS the native Plex client is trash; you're actually better off using the web app at app.plex.tv.
