In Week view of the Scheduler, event columns are out of alignment with the column headers on tablets/mobile. It appears this is because of the difference in the way the scrollbar is rendered on devices vs desktop.
To reproduce, go to the Overview demo at https://www.telerik.com/kendo-angular-ui/components/scheduler/, put your browser in Responsive Design Mode, and change the scheduler to Week view. Oddly, Month view has the same problem in the demo, but it works fine in my app. I only have the problem with Week view.
