Problem with the "live test" in the thunkable app

I’m building an app, and everytime I test it on “live test” or “preview”, the design looks ok.
But when I try it on the phone app (I have an android) the design looks totally out of place, elements out of the screen, totally unusable. Even changing the elements size, for example, shows no change in the phone screen, while it shows change in the other live screens.
What can be the problem?
Thank you!

Could you please try to use Resize Mode: “Stretch” instead of “Float in place” on each component?

Hi! Thank you for your help, but unfortunately it is still not working properly, it only made minor changes.
