why cant i trade in my apple watch
I have an Apple Watch Series 7. I tried to trade it in for an Ultra and it asked for the serial number. simple. I put it in. Apparently it was wrong. I make sure it was right and that I hadn't spelled it wrong. I checked it again and again. I refreshed the page and typed it in again. Wrong.
What do I do?
Apple Watch Series 7, watchOS 9
