We have a HTML5 app that need to be work offline as well.
Recently we noticed app is no longer get cached in Chrome 48 in IOS 9.2(ipad)
The app still works(get cached) normally as it used to be with Safari in IOS 9.
I have noticed application cache has been depricated by Mozilla https://developer.mozilla.org/en-US/docs/Web/HTML/Using_the_application_cache , but Chrome has not indicated that they have removed support for this and Chorme in other OSs works fine. Can someone suggest how to fix this issue or where to look at.
This is a limitation of WKWebView. See this Chromium bug and the related WebKit bug.
