Hello Esri Community,
Can I change the layout for the phone view in the self-design scale? Like the below pictures, I have a bunch of widgets in my web App, but in phone view mode, because it's too small, it's hard to customize the layout. I wonder if it can be like PowerPoint
; I can view it as 200% of the original and change the layout.

Also, can I preview the Web App (Phone mode or iPad mode) directly on the computer with the preview button?
Any clue or help would be greatly appreciated! These would greatly help create a more compliant App with a low code or no code environment.
