I am trying to set up the app "Workday to Active Directory User Provisioning" in Azure AD. The purpose of this app is to enable the automatic provisioning of users from Workday into on-premises Active Directory. I already have Azure AD Connect set up and running. I am following the Microsoft public documentation (https://aka.ms/workday).
I have one on-premises Azure AD Connect Provisioning Agent running (screenshot from Azure AD,screenshot from the on-premises server).
I have also tested the connection from the "Workday to Active Directory User Provisioning" app in Azure AD to Workday's API, and that also works (screenshot).
However, the synchronization service in this app in Azure AD does not appear to start. The "Provisioning" section of this app in the Azure portal still shows "Initial cycle not run" (see screenshot).
I already tried toggling the Provisioning Status from Off and then to On again (after clicking "Save"), and have already tried checking the box "Clear current state and restart synchronization."
Additionally, under Audit logs, there appear to be no attempts at synchronization (see screenshot).
So there appears to be no synchronization attempts after several hours. Under the Microsoft public documentation on "Troubleshooting user provisioning - Provisioning service does not appear to start" (link), the only guidance is "It is likely that the service is running but has not completed an initial synchronization yet." However, this lack of synchronization has been going on for several hours, and seems completely unresponsive.
How can I trigger synchronization for "Workday to Active Directory User Provisioning"?
