Goals

I want to know the real access token expiration date.

Expected results

When i has an access token i can't check the expiration date.

Actual results

When i login on IOS using classic login the expiration date of the access token is wrong: 4001-01-01 00:00:00 +0000

Steps to reproduce

I used the login example that comes with the plugin. The only change that i mad was add a new label to show the expiration: expirationLabel.text = accessToken?.expirationDate.description ?? Self.missingAccessToken

Code samples & details

In the `LoginDetails.storyboard` i added a new label and in the `LoginDetailsViewController` i filled the label with the access token expiration: `expirationLabel.text = accessToken?.expirationDate.description ?? Self.missingAccessToken`

I got a way to fix token expiration by just calling refresh token after successful login. This is my login flow:

• Log in to Facebook (the expiration date is wrong)
• Call token update (expiry date is now correct)
