Hello,
I only want tickets shared across an organization if my client selects to share it with their organization.
Currently, I have Settings > Products > Configuration > Organization management > Should new requests automatically be shared with a customer's organization? set to "No, don't share email requests with the customer's organization. Requests sent from the portal will not be shared unless the customer selects otherwise."

I also have an Automation that sets the ticket Organizations field to the organization per the email domain.

I then created a test ticket, with "Share with" set to "No one". The ticket was created, the organization was properly set, but it was shared with other customers in the organization. What am I missing in my settings? I do not want the ticket shared.
