I am trying out the new Firebase/Crashlytics setup and seem to run into a weird issue.
Ok, I think I solved the problem, but the solution does not seem to be the way it should work (at least I do not think).
So basically, from Fabric>Firebase screen - there is no link visible and from Firebase>Account Linking>Fabric screen - there is also no linking visible. So no linking, but your crashes will be visible in Firebase.
