In some cases, a workflow you've just created may not show up immediately in the Workflows tab or Backend Workflows tab in the editor. This is a known rendering behavior — the workflow has been created, but the editor doesn't always reflect it right away.
What you might notice
A newly created workflow doesn't appear in the Workflows or Backend Workflows tab
The workflow becomes visible after refreshing the editor page
Workaround
Refresh the editor page. Your workflow should appear as expected once the page reloads.
