Good afternoon!
I solved the problem, downloaded the latest version of MiHome from the Telegram channel https://t.me/Xiaomi_Hyper_OS .
I didn't change the region, I found the vacuum cleaner right away.
This Telegram channel solves problems related to HyperOS.
Updated to version 20.8.13, thank you! Two problems: 1. the mute button does not work if you press the power button for a long time, 2. the battery indicator setting does not work.
