Just a few minor issues found:
- If the TV is set to launch the last used app on startup, Emby launches with a "no network error", forcing an "Ok" and sending you into the settings menu. Presumably it checks for a network before the TV has had a chance to initialize it and it should wait a bit longer, like e.g. Netflix or Amazon Prime apps.
- Occasionally not updating from server (i.e. a new title is visible on the iOS app, but not on the TV). This can sometimes, but not always, be fixed by exiting and restarting the app.
- All the colors in the app interface - not during playback - are really oversaturated, most likely related to HDR. The colors look normal on an external Emby source, whether HDR has been enabled for that input or not.
