[RESOLVED] Logic Error : Flows require all your domains to be up-to-date

Thank you for your feedback.
I got the answer from support:

Logic Flows require your site to be published to all versions of the domain simultaneously. So that’s both .webflow.io staging domain, and custom domain.

We can subsequently unpublish staging domain, and the flow will still work on the custom domain, but when we next publish, we will again need to publish to all domains including the staging domain. This is a current feature limitation of Logic Flows.
