I am using AEM together with the wordpress-plugin Digital Publishing Tools for Wordpress.
One of the issues I have is that instagram embeds are not shown. I also have third part video service that also renders into an iframe.
But I can see that youtube iframes works fine. Are there specific iframe limitations. And here do I find any pertinent documentation about this?
Armin - you should check and see if you can load this content in mobile safari? My guess is that it is a cross domain load issue
