Currently on Laravel 6 if you install Socialite and check the code on vendor, what they are using to get Facebook details is defaulted to version 3.3. You can check it in:
vendor/laravel/socialite/src/Two/FacebookProvider.php
This version of graph might be deprecated (not sure but if you check the facebook graph api explorer you can't use lower versions, only v5.0 or v6.0 as of this moment ). If ever is there a way to specify default Facebook graph version when using it on socialite?
Thanks mate! :)
