Hi,
I have a small webapp that provides all sorts of icons for the Webclip (once user decides to "add to homescreen"). However these icons are not used consistently or at all. With not consistently I mean: they are never used at the moment the webclip is created (they don't show up during the "add to homescreen" dialog) and are not on the desktop after creating the webclip -- just the tiny screenshot thingy. BUT every now and then I see users around (within our company where it's used for the tool) for whom an icon showed up after some time, but it's impossible to predict when, why and how. All the PNG resources are well accessible, and our server is anything else but slow and is accessed via highspeed Wifi and Gigabit LAN. So it shouldn't be a network issue...
Here is the related data from the index.html:
<meta name="apple-mobile-web-app-capable" content="yes">
<link rel="apple-touch-icon" href="apple-touch-icon.png">
<link rel="apple-touch-icon" sizes="76x76" href="img/appicons/icon-76.png">
<link rel="apple-touch-icon" sizes="120x120" href="img/appicons/icon-120.png">
<link rel="apple-touch-icon" sizes="152x152" href="img/appicons/icon-152.png" >
<link rel="apple-touch-icon" sizes="180x180" href="img/appicons/icon-180.png">
<link rel="apple-touch-icon" sizes="192x192" href="img/appicons/icon-192.png">
Plus there's a 192x192 icon in the root called apple-touch-icon.png as fallback for older generations.
This shouldn't be rocket science and it worked in the past. Some new issue in iOS 9?
