How to enable /etc/update-motd.d/ messages to show on SSH login

Question

I have two servers running Ubuntu 22.04.4 LTS. One of them (let's call it host1) I will be greeted with the motd upon logging in via SSH as shown below. However, on the second one (host2) this will not show on SSH login and I only get the "Last login" info.

When I execute run-parts /etc/update-motd.d/ on either of them, it shows the expected info in both cases.
Running ls -l /etc/update-motd.d/ shows the files to be present and executable on both machines.

It is unclear to me why the behavior is different on these two systems. I'm suspecting I might be missing something trivial here.
How can I get motd to show on SSH login? Does it have to be explicitly enabled somewhere?

By the way, I noticed that PrintMotd is set to 'no' in /etc/ssh/sshd_config on both systems. Not sure if this is relevant at all, as host1 is displaying it despite being set to 'no'.

I do not have any custom motd scripts on either of these.

One bit of context that could explain a difference in configuration: host1 was set up via an Ubuntu 22.04 image from the cloud provider. host2 was set up using the standard 22.04 installation ISO from Ubuntu.com.
