LG Smart TV: Emby Theater 1.0.9
Windows 10: Emby Server Version 18.104.22.168
As reported here, Emby LG Smart TV app fails when viewing Live TV and attempting rewind or FF controls. Unfortunately, this degrades the Emby Live TV to only supporting pause/resume.
In Live TV mode, the Emby app really has no advantage over the native LG Live TV. Please fix the playback controls for these expensive and beautiful LG OLED TVs.
