It plasters a huge, obnoxious QR code in the corner of the video, along with forcing you to install some "companion app" that I swear I don't remember having to download the last time I installed this Add-On.

It sucks, because it was actually really good not that long ago. Downloading an older version doesn't work, by the way, the "Companion App" still spoils the video with that QR code. Absolutely abysmal.
