UploadButton works on mobile and desktop Chrome, but not desktop Safari

I’m not sure why, but in my live site, the media upload button on one of my pages isn’t working, but only on desktop Safari.
Places it DOES work:

  • mobile Safari
  • Chrome
  • Wix Editor (also in Safari)
    Things I have checked:
  • console on live site for errors, none presented
  • site is allowed popups, all good
  • site is allowed to access media, all good
  • cleared all history/cache

Everything is loading correctly and all code related to the button runs fine (nothing should be stopping it from opening a media manager anyway)
Any ideas?

You should report a bug:

(My guess is that since the html is set (by Wix) to visibility:hidden , it might cause some problem on some Safari versions).
