gave that a read. thing is though, like i mentioned, all 3 devices have updated to the same version of the Android TV Home app (2.1.3-320113730-f).
Only the Tivo Stream 4K is showing this new annoyance.
So, what makes the Tivo different?
It takes up so much screen space.
I did the "Uninstall Updates" for the TV Home, on the Tivo, and that reverted it to version 1.11.2-273432517-f (i assume is the original factory ROM version, so it probably way out of date, no idea what version it had before it updated) That removed the ads.
The only apps I have on the thing, is Channels Beta and YouTube. All other apps are removed/disabled.
I am for sure going to turn off "Auto Update" in the Play store now on my Shields.
That seems to be the only change they made to the launcher?
Not worth the update for the annoyance.
Maybe I can find previous version of the app and sideload it to update from the old factory version, though, i think it is system app, so that may not install.
EDIT: It worked. Got apk from apkmirror, last version 2.0.10-307630529-f (May 4, 2020). Side loaded and updated the built in app fine.
EDIT: Seems this new "Highlights" thing is in more wide spread a roll out now: https://9to5google.com/2020/08/18/android-tv-homescreen-ads-turn-off-staff-picks/
Also, Shields may not be getting the ads, for now:
