I have a knowledge base set up through a customer service portal. The portal works fine. Customers are assigned to it and can access the service portal and create issues. In Project settings
> Knowledge base > Access > Viewing I have selected the option for "all active users and customers can access the knowledge base without a confluence license". however, when the customer attempts to do so, the page shows the "page restricted" message and doesn't allow them access.
There are no restrictions on the knowledge base confluence space or page itself. How can I ensure my customers can access the knowledge base?
