When it comes to mobile devices the matter is not the same. The problem with Opera and Chrome is due to a native behavior of the click events of the iframe.
I tested with our dedicated for mobile devices demos (you can scan the QR in the Overview demo
to navigate there) and was unable to find any difficulties on focusing the content area.
Could you please open a proper support ticket with more details about your concerns, the encountered problems, so that we could properly understand the situation and assist you further?
