You know what I just noticed. Comparing my screenshot with the image

This is on my 4k Samsung 55' Note, it doesn't even let me enter my

My TV is not even a year old. The ads are infuriating!!! I ask them to
refund me for the ads, I keep sending them screenshots, and they just
ignore me with scripted replies. In case Google wants to look further,
