I just did so. Let me know if there's anything else I can do.

No diagnostics seen from your account. Did you click Settings > Support > Submit Diagnostics in the app?

Yes. I just did it again. I get the message "Diagnostics Uploaded Thank you! If you need to follow up..."
Okay I found it. I guess the tablet is not connected to your dvr.
What do you mean "connected to the DVR?"
Never mind. There is a bug in the diagnostics system so it didn't link it to your account.

I would advise you to try the official HDHR app and email [email protected]
They have a better handle on atsc3 issues and more connections with vendors.
We will also continue to investigate with your diagnostics

Yes, the problem occurs on the HDHR app (it shows "Audio only" in a black screen, so that app seems to be at least somewhat aware that there is some issue with the video). I enabled diagnostics, viewed two ATSC 3 channels and sent them an e-mail.
The answer from Silicon Dust is:
The Fire HD Tablet 10" (2021) supports a max of 1080p30 8 bit HEVC. ATSC 3.0 broadcasts are 10 bit, and usually 1080p60. Just not advanced enough of a decoder to handle higher-end formats.
Your tablet does actually have an AC-4 decoder built in, only of only a handful of non-TV devices that we are aware of that does.
Well, since the device can't handle software decoding it, it looks like the only option would be to set a device Home bandwidth limit that would force server transcoding... which would suck when playing other high bitrate content that could be hardware decoded.

Just change the tablet to transcode locally when viewing ATSC 3.0 what is the big deal a few clicks ?
Convenience. Seems something the client should be able to do on the user's behalf. Silicon Dust's player does recognize that it can't show video, but I doubt that the HDHomeRun is even capable of transcoding the video so I wouldn't expect it to try for server transcoding.
If that tablet hadn't been the first thing handy on which to try watching content when I set up Channels DVR, I may not have noticed this for a very long time. My Microsoft Store is messed up and I can't download the HEVC codec for Windows, so I think I'm running into a similar problem there and not sure what to do about it. It works on my Fire TV Cube (Gen 1).
I have run the client on an Apple TV 4K and two iPad2s without ATSC3 problems. I have also run it an Nvidia shield pro, along with the DVR server, But I don't recall if it was before or after the ATSC three lighthouse came up here
