Please remove the GA connection, authorize it again, and check the permissions.
Such a situation might occur if during the process of providing permissions to Improvado the See and download your Google Analytics data checkbox wasn't selected.
In some cases, it might be necessary to remove the Improvado app from a list of third-party apps from accounts.google.com before re-authorizing credentials.
