@kashuda, The good fellas over at [squarespaceWebsites][1] updated their finding in the SQS widget script which allows the Squarespace audio block to play WITHOUT opening a new window with the default IOS media player. Just code inject this into your page header where you audio block lives and all is well again. Thank god as this was driving me f**king bonkers!! Apparently is needs to be with a "domready" function as opposed to the old "squarespace:initialized"Ok here it is:
<script>
Y.on('domready', function(){
Y.UA.ios = 0; //Y.UA object have test key for different platforms.
//Setting ios value to 0 here allow to skip default Audio Block's behavior
})
</script>
