Automations not working if partner updates a cell


I have set up some automations that trigger emails based on updated cell contents. The emails go to people in my organization plus a group in a partner organization. This partner does not have any Smartsheet licences. Both people in my organzation and in the partner organzation update the Smartsheet. In the past, regardless of who updated the cell, the automation triggered the emails. Now only if people in my organization update the cell, an email triggers. Nothing happens if someone in the partner organization updates the cell.

Any thoughts?
