subscriptionBillingAttempt returns INVALID_PAYMENT_METHOD, Bug?

Thanks for the reply @matart .

In your migration doc it says

“If your current payment gateway is Stripe or Braintree, then you’ll use Shopify Payments after the migration.”

So, isn’t it true that we can just disconnect the Stripe account after migration? If what you explain is true, we then need Stripe connected after migration?

And your migration guide doesn’t work for multiple Stripe accounts?
