I’m using the Facebook SDK for Unity on an Android and iOS app. The first time a user logs in using Facebook it works fine and has them login via a web view typically. However it doesn’t seem to store the retrieved AccessToken and every time the app is run afterwards, the user again has to click Continue on a web view.
I’m just calling FB.LogInWithReadPermissions every time the app starts, but what I really want is it to only show the user a login prompt if the AccessToken has expired or is about to expire, not every time. Is there a better way to use the FB SDK to make the login process smoother?
