Post excepts?

That’s custom functionality you’ll need to create on your end. The functionality could be accomplished by using one of the content filters in https://github.com/alleyinteractive/apple-news/blob/master/admin/apple-actions/index/class-export.php

However, that’s not how Apple intends for content to be published to their service so we won’t ever be supporting that kind of functionality directly in the plugin.

Thanks for your answer!
