3D FlipBook - Not Working on iOS

Could you describe the issue, what actually is going on? Any screenshots would be great.

Users cannot flip pages when viewing the flipbook through Safari. They cannot tap any of the icons to enlarge the flipbook and safari also stops responding when they scroll to the position of the flipbook on the web page

Website where flipbook is located: https://www.the-isla.org/annual-report/

I cannot send screenshots because i just cant flip the pages, not sure how a screenshot would prove that?

Could you try to compress your PDF https://www.ilovepdf.com/compress_pdf ?

Also update the plugin to 1.13.1.
