同問。Seller support說可以把賬號升級到professional,這樣可以改發貨設置：
“You will have to update your Selling plan to Professional to change your shipping setting.
To switch from an Individual to a Professional selling plan, complete the following steps:
From your seller account, select Settings, then select Account Info.
On the Seller Account Information page, go to the Your Services section and click Manage.
Click Upgrade.”
然后我就問可不可以換到舊的界面？他說他們正在處理這個問題：
“We have alerted our specialists to your issue and have forwarded your case to their attention.
We understand that this is an urgent issue and will work hard to provide a timely resolution.
Thank you for your patience and understanding with this regard.”

不是可以改一下打印機的屬性嗎？把"portrait"（縱向）改成"landscape"（橫向）試試看
