problem new interface, version 2.712

I use an old tablet (Android 4.0.4) to display the new web interface (Contemporary) via the stock browser, but unfortunately the new web interface is not displayed properly all the information from the main screen is not displayed, not even the settings etc… see screenshot.
in google chrome on the tablet (version 42.0.2311.111) all info is displayed correctly but nothing is correct about the alignment.

in the old inteface it’s all okay.

Also, the corners in the new interface are also not displayed properly on a Nokia 6.1 (2012 model, android 10) in the official Volumio app (beta version) … see also screenshot.
