Yeah, I believe that the asterisk indicates an estimate, not a guarantee. Was the shipment delivered 3 days ago, or has it been 21 days since the payment?
Just had this issue eBay said funds by 21st, same as you, emailed PayPal 10 times, lol. Because I usually have funds releaseed two days after the item was delivered, just got my payment last night. Ugh, the world of eBay and PayPal. 👎
