Thanks, David. For some reason, I am still not seeing the site icon even after clearing my cache, but if you can see it, that’s good enough for me.
I got the image to work with your advice.
However, I did notice that the hamburger menu on mobile is on its own line and making the header quite large. On my other website, the hamburger menu is on the same line as the logo so the header isn’t too large. Is there a way to fix this?
