I've sold two items this week, both are showing as Payment initiated through Paypal, in process. Neither shows up at all on my Paypal account, and when I click on the 'view order' link, both say link invalid. What could this mean? All I can seem to find on the ebay customer support page is that payments may be 'held' if you're a new seller, or have a below standard rating (I'm neither of these thing), and in any case, it doesn't say the payments are 'held,' it says they're 'processing.'
