Hey folks, I wanted to clear up some confusing aspects of this issue: The main thing this warning is saying is some Firebase SDKs don't have symbols in them, which means stacktrace frames from those SDKs won't be readable in Apple Crash Reporting. The rest of your SDKs and app code will still be visible in Apple Crash Reporting and Crashlytics. This "Upload Symbols Failed" warning does not impact how your app runs, and does not come from Crashlytics.
