Can't Update Apple TV 4K to 11.3

I have beta updates turned on, and it shows I'm on 11.2.5. I click update software, and it downloads and installs, but then when it comes back on, it's still on 11.2.5. Any thoughts?

Ditto: Developer w/ 2 Apple 4k boxes. Both crap out 1/3 of way from step 2 of update. Tried numerous times to no avail- stuck at 11.2.5.
