Paypal Payflow Pro takes 15-30 seconds to process transaction

I have been using PayPal Payflow Pro for several months now and it often takes 30 seconds for a payment to be processed. I am running Payment Action as “Sale”, Debug Mode is disabled, PayPal Credit is disabled. No errors in my log (when debug was enabled). Magento 2.3.1
Is this an issue others are having? Any solutions?
