C1如何加joint account?

开户的时候收到提示:
To create a joint account, first create a single account. Then add the other person to that account from the Account Services & Settings menu

官网也这么说:

但是账户开好之后, Account Services & Settings里面并没有添加joint account的选项啊

好好看看seting 菜单上有加owner选项

Or call cs

确实有,找到了。

UI比较困惑,头像那里有个Account And Feature Settings,这里没法加,要选这个支票账户,出现另一个Account Service And Settings,这里面有。
