I open the developer toolbar and switch the view to mobile This issue occurs when after closing the Dev toolbar, refreshing the page then open the toolbar again and switch the view to mobile. Actual results: the screen turns white even after reverting the view to default. Expected results: It should display the mobile view of the template
Hmm, so far I can't seem to reproduce this issue. Can you be more specific about the steps to reproduce? When you say "Dev toolbar", do you mean the DevTools toolbox with tabs for inspector, debugger, etc.? Do you see any errors in the Browser Console when this happens? Does it happen every time you open Responsive Design Mode?
