I have created some Flipbooks using an image for the thumbnail. When viewed on desktop it works fine ( see image here: https://snipboard.io/CzFfju.jpg ). But when viewed on Mobile it doesn't work ( see image here: https://snipboard.io/4HgZV5.jpg ).
I have recreated these multiple times to correct, but they continue to be a problem. Please let me know what can be done to fix this.
This is on a staging server in a private directory. I would be happy to give you access, just not in a public forum. Please let me know if you'd like to view the site and how to give you login credentials privately.
