I’ve checked, it updated today at 10:41... it might be the Supporter badge didn’t display for the last period because we had an problem with some accounts*. When PayPal renewed again for the next period this morning it put the badge back because this time it was fixed. The important thing is it was valid because PayPal carried on charging.
*the problem was with the Instant Payment Notification (IPN). https worked fine, http said it had worked, but really it had done nothing!
