Hi there @Ann B,
Welcome to the Community! Great question, happy to help!
We don’t have an official timeline set to update the icon in the editor yet, but our product team has been made aware of this feature request. In the mean time, you have the option to upload a custom image of the new logo and utilize universal content to upload this across all your templates!
I am submitting another feature request to our template team on your behalf and thank you for participating in the Community!

Hey Taylor and Team Klaviyo, it’s been a while - any update on this? Many thanks
