Mi Home sync with ceiling 650

Hello everyone, i have completed the setup of my new moon ceiling lamp 650 with the yeelight app.
all work great and also integration with amazon alexa is awesome and superfast with no lag.

unfortunately if i try to sync, my ceiling 650 with Mi Home app, that can’t find the ceiling.
i have tried lots of server, included, singapore, mainland china, hong kong. nothing to do.

yeelight app is connected to german server.
