Webix JET on mobile not working anymore

For some reason, I cannot get Webix JET working properly on a mobile device.

My expectations are when using webix.ui.fullScreen and webix.Touch.limit(true):

  • Rotate will adjust the screen
  • Zoom is limited, so no default zoom in the browser (only in datatable for example)

However, it seems not to work on my mobile (iOS with Chrome). What do I miss here?
