Warning: Attempt to present UIAlertController on VC1 which is already presenting VC2

[reganApe]

I have configured Airbrake as described in the docs but as soon as my app starts it attempts to present an alert on my rootVC. But the root VC is already presenting another VC so this fails.

This is the code which attempts to present from ABNotifier.m

[[[UIApplication sharedApplication] delegate].window.rootViewController presentViewController:alert animated:YES completion:nil];

This is the failure message
