Community Sharing Sets I got an error of "Insufficient Privileges" on sandbox

Hello, I am creating a community (Salesforce Tabs + Visualforce) and when I try to create a new Sharing Sets I got an error of "Insufficient Privileges", this issue happens only on sandbox. There is something that need to be configured ?

After disabling the High Volume Portal User licenses, you will get an "Insufficient Privileges" error when trying to Edit/Delete or Create Sharing Sets. 

You do not have the level of access necessary to perform the operation you requested. Please contact the owner of the record or your administrator if access is necessary. For more information, see Insufficient Privileges Errors.

Resolution

This is expected behavior. Salesforce is working to hide the Related List if no licenses exist for the org.

Hello Sonam I see, so I guess I will have to go with something custom to overcome this issue, share some records with cummunity users.
