I've yet to see anything actually broadcasted in 4K though. Side note though, the ATSC3.0 channels do work in the Channels iOS/tvOS apps, as well as the HDHR native apps (with Audio).

I tried adding the ATSC3.0 channels with the ATSC1.0 Channel Guide data, but the ATSC3.0 channels don't even show up in Plex, regardless of guide info being available. Whatever TV Guide provider Plex is using hasn't been updated to reflect the new channels. The new channels actually do show up during setup, but the channel matching with Guide data doesn't show any of the new channels (100-200), and you can't re-use an existing channel (in KC market they are still broadcasting both ATSC1.0 on 0-100 and ATSC3.0 on 100-200). They recently rolled out ATSC 3.0 in KC last week, and I was eager to test in Plex. It does receive all the ATSC 1.0 channels perfectly. I have the HDHR5-4K (Connect 4K), which is the early adopter/beta of the Flex 4K.
