I was presented with this captcha before completing an online purchase this morning on my phone. The window is too small to see all of the images or the “Verify” button.
I did eventually realize that I can swipe upwards to scroll down a bit and see the rest, but there’s no visual indicator to do so. It took me a bit to figure it out.
OP encountered this on his phone. Eventually realized swiping will help you to see things that are off the current screen.
So essentially irritated at basic phone functionality.
This is why I carry around a 80" flat-screen.
