Automating emails with third-party integration

Hi! I’m a new user to Monday.com trying to set up automated emails for my organization’s online donors. I am using Zapier to connect our donations platform, QGiv, to Monday, and Gmail for the automated emails. I have had success with doing this when I am the owner of the automation, but if I transfer ownership to my supervisor or if she generates the automation, it stops working. Contacts are still imported from Zapier, but the email does not send. I’ve tried duplicating the automation and tried deleting it and having my supervisor recreate it, with no success. Does anyone have tips on possible solutions?
