Extended header problem
I just had a call with Microsoft support team and they told me that in order to use the newly released features, your SharePoint tenant should have the latest updates/upgrades (Those are managed by Microsoft only).
Also, the feature has not rolled out completely to all the tenants. So, they told me to wait till December end so that this will be rolled out to all the tenants and till then my SharePoint tenant will also get latest updates.
Hope this helps!
