Re: Not Serving yet for the past 16 hrs
If this is a new account, be aware that all ads have to go through approval before they're allowed to serve traffic. Depending on the workload (and the industry you're advertising), this can take 2-3 days to complete.
The only solution is to leave your campaign and your ads in place (don't make edits) and give the team a couple of days to get to them.
