I have the same problem. I have submitted my app with logic that actually checks the users age (MyOpenSpace.Person.Field.AGE) upon viewing the canvas page and kicks them to their profile if they aren't 18+.
This has been rejected 5 times. I believe this is happening because the person who is reviewing it is not logged in to a user with age < 18.
Please take a closer look at my changes before casting the ole' , "Again submitted without review... [ rejected ]"
C'mon... I know you got it in ya
