Buying Airpods from a private seller
Hi,
I am in the process of buying Airpods from a private seller. To authenticate the headphones I used Apple's https://checkcoverage.apple.com/ website. When I put in the serial number that the seller sent me, I get a "Purchase date not validated" message. What does that mean? Should I be worried about it? The seller has bought the airpods on amazon.
