It is rather worrying that:
a) PayPal broke something so fundamental as subscription payments. Don’t they have proper testing before they roll out changes?
b) It still wasn’t fixed 12 days later.
c) PayPal seem completely unresponsive to requests for information from developers when problems occur.
UPDATE: 2009-12-17: A terrifying and Kafkaesq story of Paypal shutting down an indie developer’s account, because of a spike in sales due to a bundle sale.
