I have opened one of my classic templates to update to the new editor, however, the ‘Switch to New Editor’ button isn’t at the top right corner as it appears in Help instructions.
Solved

Hey
Saw this in the same article:
The ability to convert a classic editor template to the new editor is currently available to a limited number of accounts, and will be available to all Klaviyo users by mid-September 2022.
Will have to wait only a few more weeks!
