Yes! If you’d made some edits on a Workflow or a Page and published them, but then want to revert back to an earlier version of that item, you can!
On workflows, this works if you’ve published changes and you haven’t updated your workflow runs to the latest version yet.
You can revert to an earlier version of that Workflow from its activity feed (the activity feed on the workflow, not in the organization settings area).
You can also restore a Page to an earlier version from its activity log.
