I just had a customer register using a Pro Form checkout page. It appears everything went smoothly, except that PayPal processed payment for the transaction twice within 2 minutes. Only one subscriber account and one recurring billing subscription were created, just the payment was processed twice.
I saw that there had been an issue with Stripe on this, but I didn’t see that anyone has brought it up for PayPal. I was a couple of updates behind (I was running v191022 until I updated it just now), but I didn’t see that anything had been added as a bug fix on this, so I thought I would mention it. In 8 years, this is the first time I’ve seen this happen. I don’t know it’s a fluke, or if something has changed that needs to be addressed.
Thanks for any input!
