Hi!
I understand your pain points. There are lot of things for which your Ad might not get approved still as being original. During the ad review process, they check your ad's images, text, targeting, and positioning, in addition to the content on your ad's landing page. Your ad may not be approved if the landing page content isn't fully functional, doesn't match the product/service promoted in your ad or doesn't fully comply with the Advertising Policies.
Anyways you don't need bother about his thing at all. I will be with you to set up your Ad till it starts running in the Ad manager.
Thanks!
