@nathancoffey in my case it will really stupid actually… Under Popup settings, there is a checkbox ‘Disable this popup on mobile devices’ which I didn’t notice. I hope it can be fixed in your case as easily as in mine!
@mariatogonon thank you for your answer. Unfortunately, that didn’t fix the problem. Moreover, using that approach for other elements doesn’t seem to work either, even on desktop…
Thanks for your replay! In the HTML, the place where the icon should be, does not contain anything… I am using the icon within a repeater group, does that make a difference or is that not relevant?
