The method definitely works in China
A couple of days ago, Xiaomi representatives mentioned that advertising on the company’s TVs could be turned off, and now they’ve told us how this can be done.
How to disable advertising on Xiaomi TV? The company itself explained how to do this
In fact, nothing complicated, but you will have to communicate with technical support through a proprietary mobile application. You need to request to disable advertising and provide the MAC address of your TV (this can be the MAC address of both a wired and wireless connection). In some cases, you will need to give your phone number or enter your Xiaomi ID. After this, advertising will be turned off at the other end, but this may take 2-3 days.
