We are facing issue only with windows after instalting the appx.
The package before uploading to phonegap is working fine with all browsers (IE, Chrome, Safari and Mozilla) when hosted.
But when we are accessing it on local machine from local drive it is throwing error "Unable to get property storage of undefined or null reference" on IE/Edge.
It seems with IE/Edge it can not able to access localstorage when not hosted. Works fine with other browsers.
