New to PVA resources. My company purchased a PVA GCC license and trying to figure out how to assign user to get access to PVA site. Tried a few different scenarios and user still does not get access to PVA site. Any help would be appreciated!!

Please make sure that your company has purchased the FREE user license for each of your users.
