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.
I do all my web development on a $4000 Mac!
Just look at all my lovely color choices!
