Why can't enter more than four digits for the lock screen password after transferring data to a new Xiaomi Pad 7?

Thank you for your continued support of Xiaomi products. If you're unable to enter more than four digits for the lock screen password after transferring data, you can turn off the device and then enter recovery mode by simultaneously pressing and holding the Volume up button and the Power button to reset the device.
Then, you can resolve the issue using any of the following three solutions:
1. After data migration during the initial setup, change the password in the system before locking the screen;
2. Before migrating data, change the lock screen password on the original device to a pattern, mixed password, or a 4-digit numeric password;
3. Skip the data migration step during the initial setup and transfer data after entering the system.
