Webpage appearance on Mobile

Hello,

i am sure that doesnt affect me only so i want to open a thread on that. When using the KE Portal on my mobile (iPhone 11,latest iOS 13 Version) the left pane overlaps the central which leds to not be able doing changes. I was working at the weekend and wanted just to turn on OOO for Monday / Tuesday. That was not possible as the left pane didnt slide up as it may should or do when i am using Browser on my Workstation.

Here is a Screenshot

May this could be change to look after new tasks or set OOO while away from Keyboard.
Not sure if this happens on Android as well, doesnt have one.

Kind Regards,
Martin
