Missing customer name and address data in SP API response

I'm having the same issue. Did you ever find a solution? Its worthless to us without the company name and address.

Yes, I found a solution:

In my Developer Profile (https://sellercentral-europe.amazon.com/developer/register)
the role "Tax Invoicing" was not selected.

After activating this option and re-submitting the form, data for name and address is available now using SP-API.

I had to setup a new IAM User and app client with access for this role.

Updating an existing app client with the new role did not work for me.

Hope this helps you.
