Unfortunately Xiaomi seems aware of the problem since the beginning (more or less 1st January), but the problem is still there and nothing has been done so far. Many people from different countries sent feedback and report about this, but no new firmware until now.
The last news was on 13/03/2021 when support said to a user "Thank you for you contact, our engineers are fixing it, and it is expected to return to normal next week". I don't even have to specify that nothing happened, do I?
