Re: Extended Approval - Creator to Manager to Manager's Manager
Hi blalor1,
When using the action “Get manager”, we should fill the Manager field of the user in Azure Active Directory.
Have you filled both the two Manager fields in Azure AD?
If yes, you could consider to use two “Get Manager” actions in your flow.
Get manager1 will be used to get the creator’s manager.
Get manager2 will be used to get the manager1’s manager. When configure Get manager2 action, use the dynamic content “Email” from the action “Get manager1”.

Hope this could be a reference for you. Please try it on your side.
Best regards,
Mabel Mao
