Offline saving - End User Monitoring
Do you have network issues? The JS errors that are caught offline can be stored locally with the help of the function provided by Real User Monitoring tool, Atatus.
More often, environments like WinJS, will not have a stable internet connection. In that case, the javascript errors, caught offline can be locally stored. Once you get the connection up, you can find the errors saved in the local storage.
Offline saving by default is disabled. You can enable it after the config() call.
