I am getting an Insufficient Privileges error when logged in as a System Administrator when trying to create a sharing set in a Community
|Knowledge Article Number||000199538|
|Description||After disabling certain 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.
For an overview of, with which licenses, you can use a sharing set, see the following documentation:
Sharing Set Overview
|Resolution||This is expected behavior. Salesforce is working to hide the Related List if no appropriate licenses exist for the org.|
