CrashLytics prints some log message after initializing and crash logs are emailed

When i try initialize CrashLytics i get Log message.

[Crashlytics] Version 3.0.9 (54)
[Crashlytics:Crash] Reporting is disabled
[Crashlytics] Crash reporting could not be initialized..


[Fabric with:@[CrashlyticsKit, TwitterKit]];

I also tried

[Crashlytics startWithAPIKey:@"my long key"];

Any idea guys whats is happening..I ve my crashlytics and Twitter fully updated.

Where to see Crashlytics Logs?

Crashlytics associates the logs with your crash data and displays them in the Crashlytics page of the Firebase console, under the Logs tab.

How does Firebase Crashlytics work?

Firebase Crashlytics is a lightweight, realtime crash reporter that helps you track, prioritize, and fix stability issues that erode your app quality. Crashlytics saves you troubleshooting time by intelligently grouping crashes and highlighting the circumstances that lead up to them.

Being faced with the same issue some time ago I finally found a solution. Make sure that you have specified correct API key as shown in screenshot attached. enter image description here
