Web export local folder -> canvas size issues

Hello Guys,

when i export my project to “web local folder”, on pc the width of the canvas resolution seems to be bigger as i configured it in GD. The result is, that my game takes place just in the left half of the screen. The right half is empty (but canvas area).
When i try it on my phone (ive uploaded the game folder onto my server) the exact opposite is happening: the canvas is to small to fit the whole game. I only see the left half of my scene. Landscape or portrait orientation doesnt matter.

Does somebody know how to fix this problem?

For others who might face this problem:
The problem was, that I had “fix the width” in the main game settings enabled. Setting it to: “no fixing” has solved the issue.
