The Viewer and the downloaded product show 2 different results

Hello, i have a problem designing an app for the phone. The viewer on the browser looks way different from what i see on my phone. I installed an ai companion on my phone and link it to my laptop when i develop the app, but the 2 products look different.

The Designer view is not an accurate representation of how your app will look on a device, this is why you need the companion app (or to compile your app and install).

Design for devices, not the Designer.

ohh, thank you that helps a lot, i thought mine was just weird.
