Failed to load. Item not found on each Channel

Kinda curious as to what caused this failure. My Tablo was working great on Apple TV up until sometime late last week (11 thru 15 Dec).

Did Apple TV or Tablo push a software update?

(I’m new to the Apple TV world and don’t know if Apple automatically pushes updates)

Hoping someone at Tablo can provide the pathology.

BTW, I’ve been running Tablo for about a month now and I’m pleased with the way it works on Apple TV (I just bought a new 4th gen).
