Is it intended that any other account other than the server owner cannot use the new player?
Edit: It looks like that the secondary accounts that do not have Plex Pass are seeing this issue. Looks like the new version is not inheriting the Plex Pass subscription status from the server owner account.
I tested it today. I tried to re install the app and tested it on 3 ATVs. Do you need any other info from the player?
Edit: Just re-confirmed. The option is not in settings to switch it either. Once I switch accounts back to the server owner it is present and I am presented with the Try it out modal.
