Our Logo has some Whitespace at the top and bottom and I want to have the logo image a bit bigger. I already tried to use 2x to 4x logo but it seems to be scaled down all the time. Is there a way to change the image size within the theme settings?
Please try to unset the retina logo option because i see you use the same logo for the normal logo and retina logo. For retina logo, you should use 2x dimension of your normal logo. For example, if you use 200px X 50px for the normal logo, then you need to use 400px X 100px for retina logo.
