Webflow requires you to republish your Webflow site any time you make a change to the CMS (eg. add a new field to a collection) in order for syncing to work.
Webflow sites need to be published to all domains for syncing to work

Only items in a "Published" state in Webflow will sync back to other apps.
Whalesync supports multi-reference fields out of the box! See the guide below to ensure this is configured correctly:
Use a powerful Airtable database to control your Webflow CMS
