The Roku 4 was dead before they ever released it.
If you have one - hook it up - install the app and give it a go.
There’s only one (well, two) Plex Apps - The Public and The Preview:
The Public is in the Channel Store.
The Preview is a private channel:
You’ll find out really quickly what’s gonna happen - and I don’t know what’ll happen. Never owned one. I went from a Roku 3 to an Ultra.
If you have a Plex app on the Roku 4 already - it’ll update to the newest Public as soon as you hook it up. If it doesn’t - invoke an update manually - System/Update
