On my ‘Ads Manager’ it indicates that my latest Ad is ‘Pending Review’, however I have reached a small number of people and spent a small amount of budget. How do I know if it has been approved and is being advertised?
According to Facebook, ads should take around 24 hours to be approved.
Did you make a change to an ad you were already running? If so, that’s where the reach and ad spend may be coming from.
If your ad has been pending review for more than 24 hours, you can submit a ticket to Facebook here https://www.facebook.com/help/contact/515460121837726/?ref=u2u.
