Flipbook is a very nice addition. I do see an issue with Full Screen which does not work, at least for me. Clicking on the full screen icon does nothing. (I see you guys are already on it, thank you!)
Please also have an option for user to download the PDF.
Hi @user2618, thanks a lot for your kind words!
Thanks a lot for bringing this to our attention! This is a really global issue, but our devs are already working on it. I’ll get back once everything’s fixed 
As for the download option, it would be great if you could share your suggestion in our Wishlist: Flipbook - Elfsight Community 
Hi @user2618, thank you for waiting!
I’m happy to say that the issue is fixed, so the full screen option should be working fine now
Could you please check it on your end?
