Hi, Happy New Year! 
My customer just emailed me, she couldn’t select shipping address to USA.
I sell from Canada, I selected all the shipping zone and went to setting , activated market to USA, but she still cant choose shipping method for some reason.
I have only one shipping method which is automatically calculated one.
I ship world wide. All the products are selected to physical.
I don’t know what is the problem. Please help meeee
