For KDP Accounts, how come I cannot see my Sponsored Brands and Locked Screen Campaign/Ads?

I know this will not be the most optimal for my KDP author user ?. We cannot support Sponsored Brands and Locked Screen ads is because currently, the Amazon Advertising API doesn't support these data sets.

The Amazon Advertising API is a stream of backend data that we can connect directly to SellerMetrics. That is why you need to "Login with Amazon" to start syncing with SellerMetrics.

If there are any changes on the Amazon API end we will make sure to reflect this in SellerMetrics.
