It seems that there is a problem in the dashboards view for Mobile
In the following attached image you can see how the component to select the date and time leaves the screen, this is due to the minimum width being 500px, unfortunately this parameter comes directly in the HTML tag and due to priority it cannot be changed with any CSS code in the dashboard.
Reducing it to 250 may fix the problem, the component is responsive so it will fit perfectly, just like the image attached below.
