After update to V2 and make the onboarding, when access to some subscriptions edit page this error appears:

2021-07-08T12:07:29+00:00 CRITICAL Uncaught Exception: The BillingAgreementId B01-8183465-8846395 is invalid. in /www/wp-content/plugins/woocommerce-gateway-amazon-payments-advanced/includes/legacy/class-wc-gateway-amazon-payments-advanced-subscriptions-legacy.php:428

Looks like a error that pop ups when the billing-agreement is cancelled. Need further invetigation.
