Apple TV 4th Gen Plex app ignores video setting

With some ripped blu rays playing on my AppleTV Plex app I have to change the video setting to 1080p 20Mbps from Original Quality because of the stuttering issue with some Sony and Warner BDs

That would usually work but the Plex app on AppleTV doesn’t seem to save the setting. I make the change, exit out, come right back and the setting is back to Original quality. Anyone know why this is?

Thanks

I’m having the same issue. Any updates or fixes?
