In versions of the Datadog Android application prior to v545-5.9.2, the app tags Crashlytics data with the user's Datadog UUID, with no user-facing opt-out. Impact: The Datadog user UUID and crash data are visible within Firebase Crashlytics. This UUID is not identifying outside Datadog's own systems.
