I've got Firebase Crashlytics set up in Android app. Yesterday it worked and I received crash reports. Today, however, I don't receive crash reports anymore.
I noticed the following error in the logs, which seems to be related:
19511 19511 E CrashlyticsCore: Failed to execute task.

How can I fix Crashlytics?
I don't really know what happened here, but after updating all my dependencies (incl. Gradle stuff) the issue was resolved.
Maybe it was a bug in Crashlytics, or some misalignment of dependencies versions...
