I downloaded the free version of this out of wordpress’ plugin library but I have noticed that on my iPhone 6+ I am getting just black screens and also one of my co-workers sent me this video (after re-booting his mac): https://share.viewedit.com/AZyZGJJ4tJvAQDCYiUQD6W
This is the test page: https://symphosize.com/learn-about-responsibid/
Is it because I have the free version? Is there a setting I am missing? I am happy to pay (I didn’t know there was a full version from the WP marketplace) but I want to make sure it will work before I pay.
