On June 15th, it was reported that Bing Ads added the ability to check ad disapprovals, as well as the ability to edit text ads and landing page URLs in its iOS and Android apps.
You can find disapproval notices on the dashboard. If you drill in, you’ll be able to see the disapproval reasons and request an exception review or edit the ads and resubmit them for review.
You can even get alerts about ad disapprovals if you have push notifications activated for your device.
