CSS animation (transform: rotateY(180deg);) works perfectly except in Chrome on iOS

Viewed 331

Long time user, first time poster.

The animations work perfectly on PC and on iPhone firefox/Safari but not on iPhone Chrome. (upto date).

The animations just appear to snap to the end location after the animation duration. I did get it working briefly however I think it was due to it caching an older version of my CSS. and I'm not sure which one or what was different. Point being i know it can work.

Any help greatly appreciated. I cleaned up the code as best I can. The working code has comments EVERYWHERE. There is a little more to the code but this is the core of it.

also running Bootstrap4 for info.

$(".flip-card-inner").on('click mouseenter', function () {
    // $(this).css("animation-play-state", "initial"); // pause Y axis rotate
    // $(this).css("animation-play-state", "paused");

    $("div.link").each(function(index) {
    $(this).delay(150*index).slideDown("fast");

    $(".flip-card-inner").addClass('fliptoback');


    });
});

Restarted Chrome. Now works fine. I want to scream.
