A user that signs up via Twitter is not granted their twitter profile avatar. Under SSO for that user in the Discourse UI, the information appears to present and correct:
And the link of their Profile Picture URL (http://pbs.twimg.com/profile_images/654649015804432385/2cliRPbF.png) is correct.
But their Discourse profile picture is the default letter image. Anyone else experience this, have any suggestions?
