Limitations

Exit URLs are primarily designed to provide useful feedback to the end user on why the application stopped working. They are not a reliable reporting mechanism for the app owner.

An exit URL is loaded in the device's main browser and could end up as a lingering browser tab/window until the user closes it. This can cause the browser to trigger additional page loads of the configured URL when the user activates the browser at a later point, flips through the various tabs/windows, or uses the back button to revisit the page. This behavior can lead to misleading statistics, if you track page views on your server.

Furthermore, App Shielding cannot guarantee that the URL is ever loaded. For example, the user’s device could be in flight mode and would not have a connection to load the URL in the browser. Thus, you should not rely on this feature as a way to collect data on security issues.
