I have a specific header image design that displays the name of my blog. In the free version, I was able to upload the 1200×528 image and hide the site identity/tag without issue. Now that I have the “pro” version, the header image shrinks when I remove the site identity & tag line text and does not display the full 1280×528 image. Once I show the text, I have the full header image
I have also inactivated the Top Page Nav for the 2nd menu & search bar and the issue persists. I have a much smaller header image now than shown in the demo version.
