Orders' phone is null

We are trying to retrieve the phone number from the orders we are receiving, and on the Store backend the phone number is visible, while querying it via GraphQL it is null.

We don’t think it’s a permissions issue as we would have gotten an error instead of just null…

You most likely need to request access to protected customer data.

As I said it’s not a permission issue or we would have gotten an error in the API response. Also we are already receiving correctly the addresses and the email, but the phone remains null, despite being present in the order
