We’ve improved the functionality of the buttons that help you navigate through the workflow composition steps.
When viewing an email in the builder from within a workflow, you can now click back to the workflow using the ‘Back to Workflow’ button without having to navigate through the email composition process. Please note, however, that this will discard any changes you’ve made to the email. If you want to save changes to the email, you will still need to proceed through the email composition steps.
The copy-and-paste option on list imports should be working as expected again.
