4.10 modern interface - bug?

Hi, i Just tested the modern interface, and here is a bugreport from me:

Modern interface is not working for me (ver.4.10)
The active clients are not shown as active. I am not able to change the language.
I am also not able to use the button (settings, notofications, etc.). They are grey.. not possible to click on them.
I am only able to click on "route".
I used different browsers on android and on a windows pc.

Grayed out functionality is not implemented yet. It is just a preview with very limited features for now.

Thank you for your response.
An also thank you for the great software

Wish you all the best
