Re: During ad creation the preview is not available
Welcome to adwords community!
As per your subject line, I assume you want to see your ad preview at creation time which is not possible. If you've just created or changed an ad, remember that it might need to be reviewed and approved by Google before it’s eligible to run. You can see whether your ad is under review by looking at the "Status" column of your account's Ads tab.
Hope this helps!
