Switching a flow from the old editor to the new one is very easy.
Enter your flow and click the ☰ menu icon in the top right corner:
Next, choose “New Editor” from the dropdown menu:
Your flow will instantly switch to the new editor. You’ll immediately notice the new, streamlined look.
Your flow’s expressions will be different, but you should not see any issue with how your flow works. Be sure to take a look at your flow’s nodes to see how those new expressions are written and how actions and Split Actions now work.
Of course, we always encourage testing your flows before sending to your contacts!
