We observed for images in Android we are seeing 404(Not found) errors if Image not found and it’s captured in MobileRequestError but in iOS nothing captured in MobileRequestError if image downloading failed.
Sometimes when we see this happening, it is because of a network object that was created before our agent began instrumenting and that rouge network object is handling these network calls; in this case, such a networking object may be handling all the calls somewhere else.
In order for the New Relic agent to instrument your app correctly and track all networking objects, the agent needs be the first thing that happens after the application launches. Could you walk me through what is happening before calling
application(didFinishLaunchingWithOptions:) , if anything?
