I don't think this should be treated as a duplicate since the first question didn't get a proper answer
I have a WP page running and for some reason I can't get Edge to display the favicon. It works everywhere, even in IE11. The first two lines are mine, the others are generated by WP. I doesn't work on deployed server either.
<link rel="icon" sizes="16x16" href="/favicon.ico" type="image/x-icon" />
<link rel="shortcut icon" href="/favicon.ico" type="image/x-icon" />
<link rel="icon" href="http://192.168.1.59/wp-content/uploads/logo.jpg" sizes="32x32" />
