Why my app icon is not updated in MIUI or vivo launcher?

Question

我将应用程序中的应用程序图标更改为mi或vivo手机时，启动器中的图标不会更新，即使我重新启动它或更改主题也是如此。

This is probably caused by a crappy theme manager. Just change the theme, or if the phone is rooted, search for your package name under /data and delete the cached files. There's not much you can do if this happens on a user's device.
