MailChimp Landing Page Plugin Failure

Hi,
I have the latest version of WordPress set up on Amazon Lightsail. I have installed WooCommerce on this WordPress website and connected it to Mailchimp via the plugin ‘Mailchimp for WooCommerce’. The connection was successful and I can view this ‘connected site’ on my mailchimp dashboard.

The issue is when I come to creating a MailChimp landing page. I’m trying to add a product through the Landing Page editor. It finds the product correctly by name, but when I hit ‘save’, nothing really happens. And when I publish the landing page, everything except the product shows up.
