Hi Chris,
I have also posted this in the Google publisher center community. Yes, the feed is working pretty fine for you, for us but not for Google. I had a word with Google news support team they said the feeds have these following issues:
`We request you to add the required tags correctly as per the requirements mentioned in our guidelines. Also, we noticed that you are using both <description> and <content:encoded> tags in the feed URL of the publications. Instead, we suggest that you use any one of the tags. If both <content:encoded> and <description> tags are present in the feed, Google News drops the tag with the least number of characters.
Also, there are few requirements which need to be followed while adding the image to your content, they are:
The images should be a minimum of 800 px on a side.
The hero image encoding should be done using the <img> tag and the attribute class should be: <img class=”type:primaryImage”>`
I replied to the Google team that the feeds already have this type:primaryImage tag in the feeds . Google Team said they have escalated the issue to the relevant team. God knows when they will fix the issue.
