[VLSessionManager loggedIn] does NOT work

[Supertecnoboff]

The following method [VLSessionManager loggedIn] only works when the user is not logged in. However if a user is logged in and they revoke app access via another device/Vinli website, the [VLSessionManager loggedIn] method, still thinks the user is logged in. This needs to be fixed, as not all methods have a failure block with the necessary parameters that state, whether or not the user is logged in.
