I have exactly same problem. I choose the cheapest in fedex it works but
didn’t realize it took so long to arrive bec label is USPS but I choose
fedex. Hope eBay will fix this issue
I did tried to change the address, I even involved my buyer and said she
has no problem before purchasing eith address age gave..keep saying
invalid state but fedex works. But I tried in my laptop, it works too
I have the same promlem, but the messsge says invalid state. I tried in
my laptop it works. FedEx has no problem only USPS. So I guess USPS has
glitch on IOS system.
