Promblem about objets position

When I use the website-test everything is ok and in the same position. When I use the app on my smartphone to test my app nothing is where it should be.
Something change position or something has a strange resize.
How can I fix it?

(I use android system)

Hello @guido.stefano90x3o

Are you building with the old snap-to-place interface or the new drag-and-drop interface?

The new drag-and-drop interface

@guido.stefano90x3o Try to change the height of each row/column to “Fill Container”

I don’t have row or column, it’s just drag and drop
