I have created an app in the new marketplace, an Account-Level app. I have ALL scopes checked. When I authenticate (or re-authenticate), I get an access token successfully and am able to use it until it expires. However, when I try to refresh it using my refresh token, I get the following error:
Invalid request : Unable to narrow the scope of the client authentication to requested scope.
It was working fine up until recently. I am unable to find any answers about this error message anywhere else.
