Issue
In multi-brand portals, it is currently not possible to enroll a contact in a sequence if they are already enrolled in a sequence belonging to another brand.
Expected behavior
Contacts should be able to be enrolled in different sequences across different brands within the same portal. Since each brand operates independently with its own communications, this limitation is not logical for multi-brand environments.
Business impact
This restriction prevents teams from communicating with the same contact on behalf of different brands, even when those communications are unrelated. It creates unnecessary operational constraints and is particularly frustrating for organizations managing multiple brands from a single HubSpot portal.
