Not no more my friend there no auto review anymore , terriost stopped that ...There are two types of reviews, if it is ad review, they will go to automated review and then, they will also go to manual review. But usually it will get approved within 1-2 hour and not more if it is manual review for most of the ads.
If you take about account review, it comes under billing issue, sometimes new accounts go under review for 2-3 days and they get suspended even if its legit.
So billing review and ad review are completely different.
Mine was auto approve but then they suspend after sometime and they reviewed and they found nothing...and unsuspend the account..the review im talking about is after the auto review, where they accepted the ads but then they suddenly say take 1-3 business day for manual review.
