To continue using Crashlytics, make sure to upgrade your apps to the Firebase Crashlytics SDK versions 17.0.0+ for Android, 4.0.0+ for iOS, and 6.15.0+ for Unity before November 15, 2020.
We have received this mail from Google/Firebase team. I can see upgrade packages for native Android/iOS. But are those corresponding latest packages available now for my Xamarin.Forms app?? I couldn't find proper information on this with 15 days or so remaining to work on the upgrade. Any help please?
