Revisions not showing despite being enabled for pod

Hello, Pods People!

I’m having an issue with a Pods CPT where revisions are enabled, but are not displaying on the edit screen. I’ve been doing a bit of digging and am wondering: is it still true that custom fields don’t ‘do’ revisions? And that it would only be the ‘editor’ that would trigger a revision?

The Pod in question is 100% custom fields, with no editor, so I’m wondering if this lack of revisions is a result of that peculiarity or if it’s something else.

Thanks very much for your time.
