End user custom fields not updated when end user is created using Azure AD Provisioning

Hello,

We are creating our end user using Azure Entra Id (Azure AD) provisioning. In addition to the standard fields, our end users in Zendesk have two customs fields [type] and [office_location] which are populated by  Azure Entra Id. We have noticed that when the end user is provisioned/created into Zendesk, the custom fields are not systematically populated. After creation, if the same end user is updated, the custom fields get populated. In the Azure Entra provisioning log, the custom fields are populated. We need to use the custom fields to build some custom reports and because of this bug, the KPI's are wrong. Is there anything we can do, other than to provision on demand end user when the custom fields are missing?
