Hi Josh,
Thank you very much for the details!
I looked through the documentation but I could not find any functions reference or API. If you have access to their support, can you please ask them the following:
Is there a way to programmatically check if the current user can access a specific post by ID?
Something like user_can_access($post_id, $user_id) or anything similar.
That is all I need 🙂
