You're right. They add it to your homescreen without asking, and then one of the kids clicked on it. It's not a terrible app, actually, I just resent having to turn off all the bullshit they keep adding to my home screen. Once I realized that someone had enabled it, I picked some images that weren't too bright or distracting, and left it alone because I figured why not? Then I walk into the room where someone left the tv on, and it's got this qr code across the bottom.
Thankfully, there wasn't any burn in, but still. It felt like a "Beware of Sign" sign.
