Looker Studio: Fit to Width Problem

[TossBi]

I already set the page of my report to suit with the smartphone screen (Screen 16:9, Vertical, 768*1366 px).

Unfortunately, when I see the report via in-app browser or chrome, it doesn't fit to the width of the screen. I carefully check with the display option in 'Theme and Layout' of my report to check on the "Fit to Width" already.

Can any one help me fix this problem.
