The box shows up (if I tell it to show the frame), but no video shows at all. Tapping the area doesn’t make anything happen. It works fine on iOS 12.1.3 (and all earlier versions that we tried), but not on 12.3 or 12.4. The NON-responsive version works on 12.3 and 12.4. Here is the iframe code we use:
<iframe src=”https://player.vimeo.com/video/316188687?autoplay=1″ allow=”autoplay” width=”640″ height=”352″ frameborder=”0″ webkitallowfullscreen mozallowfullscreen allowfullscreen></iframe>
The HTML extension type is set to “other” (We have our Vimeo videos set so you can only see them from our website – I can find someone to change that for one video if that would help you diagnose this problem).
Thanks for any help you can give me! – Janice
