Does JotForm still not support API Credentials from PayPal PayFlow Pro for subsctiptions?

The error message reads "DPRP is disabled for this merchant."

We do not support the PayPal PayFlow accounts and APIs, but we do support the standard PayPal Pro accounts and APIs.

You can use your regular PayPal Pro account to accept subscription payments. Maybe this thread may shed some more light about the distinction:
