Why did I get the error "Subscription Profiles not supported by Recurring Payment APIs" when updating Recurring Billing?

A PayPal error message reported problems with subscription button profile IDs.

The basic Subscription button profile IDs aren't supported by the GetRecurringPaymentsProfileDetails API. This API works only for subscriptions or Recurring Payment Profiles created via the CreateRecurringPaymentsProfile API and through Express Checkout (our API-based checkout solution).

Collect basic subscription information via Instant Payment Notification (IPN) to store in your own databases, or view the information on your PayPal account.
