Developer mode, how activate it with the new App redesigned?

I have to set developer mode on in the yeelight bulb but I can’t find anymore how do it in the iPhone app.
Please support me because my domoticz doesn’t works anymore


Developer mode is named “LAN Control” in new version.

Can you provide detailed instrunctions please? I can’t find LAN Control anywhere. This app is needlessly confusing to use. Your help would be greatly appreciated. I just bought 6 of these light bulbs (white)

Have a look at it.
