Hi, I am generally a happy premium user and using your plugin for 3 websites (different environment) for 4 months.
It seems your plugin is not compatible with Woocommerce Membership.
When embedded in a wp post it works - obviously, but
non-members can view/search the ebooks page through 3d-flip-book directory.
-https://website.com/private-ebook <---- (normal WordPress post, for members, with embedded flip-book) successfully blocking non-members.
-https://website.com/3d-flip-book/private-ebook <--- (original flip-book page) non-members can access, even though I set this page to be member-only.
the setting just doesn't work. and I don't understand why.
