There is a little about this in the FAQs:

However, that small amount may not go into enough detail. There is a more detailed post here:

Thanks Chad. For some reason the shortcode section wasn’t showing up, but after reinstalling the plugin it’s there and it has sorted out my issue. Changing from Backend Editor to Classic Mode on the page, and using the WP-Member “Logged-in content” shortcode fixed it perfectly. After adding it you can switch back to your page builder view.
Thanks, like the other user having this issue I restored to using the shortcodes to block the content since the plugin wouldn’t block it natively even after disabling all other plugins and using the base twentysixteen theme on my staging environment.
