For reference the Channels DVR app on Android plays ATSC3 channels perfect (video & sound) in 4-5 seconds after clicking on it. On Emby mobile (3.2.47) it takes about 12-15 seconds to load an ATSC3 channel, the image flashes for a split second then goes to black. There is never any sound. Current server version is 4.7.0.37 beta
