Hi!
If existing deals have a deal probably “manually” set on the deal, that will prevent HubSpot from applying the latest % deal probability set on the deal pipeline stage.
See: HubSpot's default deal properties
- Deal probability: the probability that the deal will close. This property is updated automatically by HubSpot when a user moves a deal to a new stage based on the Win probability set for each deal stage in the pipeline settings. If you manually edit a deal’s probability, the property will no longer be updated automatically based on the pipeline’s open stages. Manual updates include updating a value on a record, bulk editing records, and changes made via data sync integrations or API. The deal probability will only be automatically set again if that deal moves to a Closed Won stage (100%) or a Closed Lost stage (0%), which can be set in bulk via a workflow.
