Hi @Jessica Reichert ,
There is currently no blade to display extension properties or on-premises extension attributes. You have to use the Microsoft Graph API in order to see them. https://learn.microsoft.com/en-us/powershell/azure/active-directory/using-extension-attributes-sample?view=azureadps-2.0
To see the updates you would need to query those attributes directly:
Select-MgProfile -Name "beta",
(Get-MgUser -UserId "[UserObjectID]").OnPremisesExtensionAttributes
If you're interested in this feature, I suggest filing this as feedback in the Azure AD feedback forum here : https://feedback.azure.com/
I would also be happy to surface this concern if you have a business justification you can provide.
Additional references:
Export all users to a CSV file with all OnPremisesExtensionAttributes
Let me know if this helps address your question and if you have further questions.
