Hi nova9 Why doesn't WeChat ring when you sleep at night?

Maybe it's Do Not Disturb or WeChat is Do Not Disturb.

Mobile phone settings-security privacy-notification center, check whether the status bar shows WeChat, enter mobile phone settings-general-security privacy-pure background, and add WeChat software to make the background run. Secondly, you can open the phone settings, find auxiliary functions, and find messages at night to avoid disturbing. If this function is enabled, all incoming calls will enter do not disturb mode at night.
