We recognize the importance of giving our mentors the flexibility to create session for different kinds of mentees they have, One of the things we did to acknowledge that is giving them the ability to create public sessions and private sessions.

Here's the main difference:

Public sessions - are visible to all via a mentor's profile page.

Private sessions - are not visible to anyone unless you have given them the private session link. Only members who have the link are able to book this session.

Hope this clears things up for you!
