HTML Editor and source code tab
We use a custom HTML template. For each block in this template, I created a universal block so we can reuse them in both campaigns and flows.
Since the new update today, I can no longer edit the universal blocks because Klaviyo seems to have removed the Source Code tab from the editor.
This means I can’t create emails anymore. Does anyone have any idea how to fix this?
