Listing renewal

I’m a bit confused by the recurring Paypal payment and the listing expiry, hopefully someone can shed some light.

I set up a 1 day listing package and posted a test listing yesterday (30th). The automatic payment notification came through from Paypal today to say the second payment had been taken but when I look in my listing manager the expiry date on the listing hasn’t changed (still set to 31st). Shouldn’t this automatically update to correspond with the payment?

The listing is still live regardless.

I’m going to stop the payment from within Paypal and check that the listing actually expires tomorrow when payment isn’t taken. I can’t see how this will work though given all of the above.

Has anyone else experienced this?

Also, when the second payment was taken I got another default WP email with my username and password – does it generate a new user password each time a listing payment is taken or is it just a confirmation?
