• Firebase Component: Analytics

When including the GOOGLE_ANALYTICS_IDFV_COLLECTION_ENABLED key in an app's Info.plist, there is no confirmation that Firebase recognized the presence of the key. It would be helpful if Firebase/Analytics could reference the presence of the key and its current value in the debug logs shown in the console similar to how other keys are handled. This would give users confidence that they have added the key correctly.
