If a product ASIN is Not approved in the Status column at the ad level, at the Campaign level and Campaigns overview level, the Status column will still read "Delivering".

I understand that the description reads "Your campaign is delivering. Ads in this campaign with a “Delivering” status are eligible for impressions." But it means you need to click into each campaign then ad group to discover if your ad is Approved or not.

When we running 200+ campaigns ... manually clicking each campaign, then ad group, to check if the ad is Approved or not, is tedious.

The notifications bell (top-right) will sometimes alert us to a campaign not running, but having the Campaigns overview report Status column clearly showing if ads are not running would be best.
