Dear user.
Sorry for the inconvenience.
Please note that MIUI 12 has released to all users of Redmi Note 8 Global and China but the users using 11.0.11.0 Global are facing the issue with the update. If you are using 11.0.11.0 Global rom, please wait patiently and try to update later.

When will you fix this issue?
