Meteorite Wifi Issues

Hello,

I can add my meteorite lamp to my yeelight app and also can connect it to my WIFI network 2,4ghz.

My problem is that every time when I turn off my connected meteorite lamp and turn it on again, it will not re-connect to my wifi network. Then I have to reset the hole lamp (5x switch on/off) and delete it from the app and make the setup in the app again. Also amazon alexa can only access it the first time, so it is not only a App problem.
As long as I do not turn it off, all functions are working well.

Thanks for your help!

Has nobody WIFI issues like that?
