Can't even get to click on recaptcha

[wrobelda]

So one of the websites I monitor implemented a recaptcha. It also shows when I use it in my own browser, so they probably flagged my IP, but its enough to click "I am a human" and it works 10/10 without getting me to solve the puzzle.

So I tried getting ChangeDetection to do the same, to no avail: no matter what I do, I cannot have it check that checkbox. The captcha itself is in an iFrame. I tried:

1. finding an XPath element (a full /html/blabla/iframe/html/element)
2. clicking X, Y
3. Clicking element by its name

Nothing works. At the very least clicking on X, Y should, right? What am I missing here?
