No, why does China UnionPay Express always send me messages?

The reasons for texting are as follows.

It is because your China UnionPay Express has not been cancelled, so the background has been operating. When it is displayed at one o'clock, if you log out in the settings, you need the account password for the next login, just like when you use WeChat, it will be displayed every time you click. This is because you have not logged off, and the commonly used software will not be logged off for the convenience of next use. You can cancel it if you don't use it.
