Do custom attributes in SharePoint user profile cards update for existing and new users?

Question

I have a requirement to show extension/custom attributes in the user profile card in SharePoint. If post calls are made to the endpoint https://graph.microsoft.com/v1.0/admin/people/profileCardProperties, will the updated properties be visible to both existing and new users?

Hi @karthikp-9576，

Per my research and test, custom attributes will be visiable for users in SharePoint user profile cards like following

And the user profile cards update will be available for all users include new created users in the tenant, Since it takes up to 24 hours for the changes to show on profile cards, currently my tenant haven't display the custom attributes. For more details, you could refer to following articles:

When you make POST calls to the endpoint for adding custom attributes to the profile card in SharePoint, the updated properties will be visible to both existing and new users. However, it is important to note that it may take up to 24 hours for the changes to be reflected on the profile cards after the updates are made.
