Why does the notification bar prompt "Uninstalled apps leave residual items" after booting and entering the home screen on the Redmi Pad 2?

Thank you for your support of Xiaomi products. The tablet undergoes strict professional inspection before leaving the factory, and you can use it with confidence.
If there is a prompt about residual items of uninstalled APPs on the Redmi Pad 2, please refer to the following details:
1. After booting up the device, the system will automatically uninstall certain APPs that are not required or relevant for the current region;
2. As a result, the notification bar will display a prompt indicating that there are residual items or traces from these uninstalled APPs. This is a normal process and does not affect the tablet’s overall performance or usage.
