I've already tried it. I don't like the web app's functionality, I prefer the normal mobile browser. The pop-up obscures the bottom buttons and is distracting, and adds an extra step to using the buttons.
I've tapped x but it keeps popping up. There needs to be a "no means no" button, a decline cookie or something, so that I'm not constantly having to say "no" like a woman at a bar continually getting hit on by some drunk dude. I can't throw my drink in the face of the pop-up.
