I'm sorry for the delayed response. JFBConnect makes most calls with the newer Graph API 3.0 version, released in May of last year and currently has no sunset date.

intentionally as that enables some other features on the front-end. v2.8 shouldn't cause any issues for functionality like authentication.
Regarding the review, we can't do anything about that. Facebook may automatically submit your app for review. If they aren't allowing ou to edit or update settings while in Review, we can't do anything about that. All we can recommend is waiting for the Review process to finish.

Alex
