This page above has a button from WebinarJam, that displays a webinar-registration popup when clicked.
Everything works super on a desktop pc.
But on moblie - and I have tested it across Iphone and Samsung, with the same results - the screen greys out but the popup does not appear.
If I manually refresh the page in the mobile browser - again, both on IOS and Android - then click the button again, sometimes the popup will apear.
The popup is mobile friendly, yet something about my setup is stopping it.
