When a recurring payment fails, Stripe retries every 6 hours, and then gives up after the 4th attempt. That is, within 24 hours, the subscription fails and is cancelled. Most often, payment fails because of insufficient funds on their credit card. If someone transfers more funds to their credit card, it can take 3 business days for the funds to clear - so it's crazy to retry so soon. They need to be at least a few days apart to allow people time to actually rectify the problem that caused it to fail. Please either let us configure when the retries should be, or else change the default to be every 1-2 days at the very minimum, if not 3+ days.
