If you have tried to add a new ad and then it takes you to the payment screen don’t panic. There just happens to be three reasons why you might be seeing that. 1) you checked to have “featured ad” 2) you chose a section that requires payment 3) you did pick a free ad but the payment screen showed up. The answer is this. If one 1 or 2 has been done then you will have to pay up lol. If it’s a free ad I have it to review and will approve it if it meets ad post guidelines. So no worries. Keep posting and just exit out of the payment screen.
