I am having trouble with my own access token, for some of my friends I can only retrieve public data. I generated two access tokens:
Both access tokens have the same (extensive) scope.
However, queries using the tokens behave differently - but only for some of my friends. The token from the API explorer behaves as expected: it yields a broad results with private information. The OAuth token seems to retrieve public information only, but only for some of my friends. For most of my friends, both tokens retrieve the same information.
