I had an issue with loading thumbnail speed on the lite version it took forever I purchased the PRO version in hope dor the issue to be resolved but I still face it and especially on mobile it took around 1 - 2 minutes for the thumbnail to show up, I used an image as the book thumbnail but it still takes forever to load.
Use images as book thumbnails otherwise the plugin fetches PDF to render it first page. https://youtu.be/COueCeQpeB4?t=12
i did use an image as book thumbnail yet it still takes forever to render

https://healthavenue.org/issue7/ this book does not have image thumbnail so the plugin render its first page - it is quite slow.
i chose the image from the cover properties tab is there another way to set the thumbnail ?
watch https://www.youtube.com/watch?v=COueCeQpeB4&feature=youtu.be&t=12 , it is on General tab, binderTexture is different - it is left part of the book between covers for LTR books.
