It seems to be related to some advertising push from a partner named Alfonso that is gathering information cross-platform anything that appears on your screen and pushing advertising to you during playback.
Hopefully not, but that’s what it looks like from early reading.
This is precisely why I never connected my Sony TV to my Wif - not even setupi. If I ever want to watch YouTube, I can use my PS4 - it will handle the 4k or 60 fps videos much better and won’t stutter if I try to read the comments. Deleted every single app that wasn’t native to android. MY TV now only does two things - either displays HDMI from my set-top-box, PS4 or laptop (for movies) or displays a nice slideshow with the time (built-in screensaver)
