Add Touch Icon/WebClip for Blogger
So, the problem that I've seem to have diagnosed is that browsers will cache favicon information, which includes Apple Touch Icons. For me, that caused my browser not to update the icons. 

What I did was add append a version attribute onto the end of the URL pointing to the image.

&lt;link rel="apple-touch-icon" sizes="180x180" href="https://yoursite.com/apple-touch-icon.png?v=1A11a1AAaA"/&gt;


Specifically, I added "?v=1A11a1AAaA" at the end of the URL. I hope this helps anyone with the same issue.
