InvalidAccountStatus on sandbox


I am currently in the amazon pay integration process, therefore I am using it in sandbox mode("s"s in the widget are present).
Despite the fact that sandbox should be usable with my account status I am getting an invalideaccountstatus error from the address and wallet widget.
it is stated in my in account info that : “Amazon Pay is Inactive. You can transact in the Sandbox environment only. Please refer to your account verification status or contact seller support.”
Is this a normal behaviour ?
