Difference in behaviour between mobile and desktop UI

Hello everybody,
this is my first articel in the in the home assitant forum.
I installed it today in a docker container on synology.

A Philips hue LightStrip+ is a part of my configuration.

If I visit my home assistant via desktop browser I can switch off/on the hue light, change the colour and brightness. Everything is fine.
On my smartphone (Google nexus 5x) I installed home assistant via google chrome on the desktop.
If I switch the light on the switch turns off automaticly but the lights is on furthermore. The option to change colour is not available in the mobile UI.
Does anybody of you has the same problem? And can anybody help me?

Best regards
