Protect content created with Visual Composer

Hi,

We use visual composer from WP Bakery to add/structure content to our pages/posts.

This does not seem to work with the membership plugin, I have tried to add the membership level access shortcode before and after the content, but it doesn't seem to be protecting the content.

Have you seen this issue before?

With S2Member, we could just set whether the page is protected or not via an option on the page/post edit screen. Is it possible to do this with the membership plugin?

Thanks

Gurdeep
