Why the downvote? It doesn’t work on iOS browsers, period. It’s a fact.
*Edit:* The previous poster specifically said they use an iPad, that's odd. Worked fine on my 12,9" iPad Pro, Display Zoom is set to "more space", i.e. more content shown. In case it has an issue with not enough screen space?
That being said, I don't think the refresh button (actually a seed randomizer) is related. I was definitely already playing around with it on my iPad when you posted your comment. However, I am not sure about the timeline in relation to the first comment (above yours).
