Mi LED smart bulbs europe

this is crazy and i find it hard to believe that out of nowhere Xiaomi decided to fuck their customers.
you wanna tell me that Yeelight has a specific batch of products for europe that doesn’t allow them to connect to China and vice versa?

i have an entire Xiaomi ecosystem connected to Mainland China which i am not planning to change to Europe as i want to be able to buy new products and actually have them work like Xiaomi’s doorbell which at the moment only works with Mainland China. If i buy a Yeelight bulb from Europe, it won’t connect to Mainland China? how the hell do they know it?
