We faced an issue with Facebook SDK when using FB.ShareLink (https://developers.facebook.com/docs/unity/reference/current/FB.ShareLink/#more-examples). We have this option to make a share with App (see attached screen). It works, app opens and user can make a share but when it's done and app is closed this login popup stays (if you do it via login from email and password, after you make a share this window closes automatically), so user has to close it manually, but in this case we will get callback with Cancel == true. Is this a bug? if no - how can we understand in this case that share was done?
