Amazon Linux 2023 new release - never happens.

When I login to one of my Amazon Linux 2023 (Lightsail) instances, I see this:

A newer release of "Amazon Linux" is available.
  Version 2023.1.20230825:
Run "/usr/bin/dnf check-release-update" for full release and version update info

Running that gives:

WARNING:

  Available Versions:

  Version 2023.1.20230825:
    Run the following command to upgrade to 2023.1.20230825:

Running the uograde:

# dnf upgrade --releasever=2023.1.20230825

Dependencies resolved.
Nothing to do.
Complete!

Suggestions on fixing this???

EDIT: Just in case, I removed the speedtest repo and did a dnf clean all - no difference.
