Multiple ad placements on a page:Only one ad placement can occur per page within your app. For example, your app can contain no more than one banner ad within the page, and your app cannot contain a banner ad with multiple offers. Update for my app got rejected and i received the above message in mail. My question is, is there any setting in Admob to control number of offers/Ads shown in a single banner ad ?.
You will get this problem if you are targeting 'families' and 'children'. It's such a hot potato with Google play. So unless you ARE targeting that audience, I suggest you either remove the banner ads and use something else like rewarded videos, or check in testing what type of ads are being displayed.
