Merchant Token?

Amazon has asked for documentation and wants me to use my merchant token/vendor code but I’m having trouble finding it.

The Amazon help page says: View your merchant token

To view your merchant token, complete the following steps:

1. From your seller account, go to the Settings menu and select Account Info .
2. In the Business Information section, select Merchant Token . The token is displayed at the bottom of the page.

However, under business information all I see is Identity information, transfer account, business address and display name, none of which have a merchant token at the bottom of the page once clicked.

Can anyone tell me how to access my merchant token please?

Thank you
