I had four ads for a particular campaign, I wanted to change the display url, so I updated them. Now, their getting no impressions... does this like reset everything and now I have to wait ~24hrs?
Your display URL must use the same domain name you have used as your actual URL. Are you sure you're doing it correctly?
yeah any text ad change will require it to go through approval again... Looks like you got to wait another 24 hours =(
Only change one ad at a time. Your ads went to a review, even though it was just the url you changed.
