Hi I was following up on an earlier question regarding the flipbook lightbox not closing on mobile versions. The close button is not responsding to repeated presses. Can you please advise? Also, I wanted to know if there was a way that I can calculate the page width and height so that the content is not squeezed. I don’t understand how the default numbers are calculated compared to actual page sizes.
