Ads are Not Approved
I uploaded text and banner ads for app install campaign of LuckyStars App on 17th of August at 6:21 pm and I was waiting for approval. It's been more than 3 days. I hope this issue get resolved and I would start running app install campaign smoothly.
Re: Ads are Not Approved
Mostly ads are approved within 1 business day but some ads may take longer if they require some complex review. As it's already been more than one business day in your case. I would suggest you to contact Adwords team for this issue.
