Feeds not recognised

The links are on the landing page.

I have set up two RSS feeds within WP RSS Aggregator and checked the settings as far as I am able to (I may have missed something):

https://www.glowweobley.com/feed/

https://www.believethegoodnews.com/feed/

The validator passes them with (what I believe are) minor errors.
The hosting company has done work to ensure that they are not blocked oin the server side

But I’m not seeing anything from the shortcode.

Happy to share my login details for further investigation — there’s little on these sites that’s confidential.
