Hello, I am posting in case this helps someone else.  I already had the logo set high according to your instructions but the logo was still tiny.  I finally figured out the issue... It was the header height setting.  I fixed it by going to Appearance > Customize > Logo & Header > Main Bar & Primary Menu > Custom Main Bar Height ... and toggle between desktop and mobile settings.  I do have another question regarding the mobile header.  I was using header 10 and had overflow on so that the logo dipped down into the content below but the overflow did not show on mobile.  Is there a place to set mobile header separately?  Thank you.

How can I make the logo in mobile larger? It is tiny. I am using header 10. Thank you.
