I'd say its not normal.. I know people who were approved in less than 16 hours... I guess it might depend on your location though
yes it is normal.. many times they may just take few days and many times they take more than a week.. mine took around 8 days before I got the confirmation..don't worry you will get confirmed any hour now.. best of luck
Work on content while waiting and plan where your ads will go once approved. Time spent now while waiting will be time saved once approved.
