-⚠️ **REMOVED** ⚠️
+# Firebase Crashlytics
+
+Modular API method `isCrashlyticsCollectionEnabled(crashlytics)` has been removed, please use the property on Crashlytics instance
+`getCrashlytics().isCrashlyticsCollectionEnabled` instead.
+
+# Firebase Auth
+
+`MultiFactorUser.enrolledFactor` has been removed, please use `MultiFactorUser.enrolledFactors`. See example:
 
-# Firebase Dynamic Links has been Removed
+```js
+const credential = await signInWithEmailAndPassword(getAuth(), 'dummy@example.com', 'password');
+const multiFactorUser = credential.user.multiFactor;
+// Use below - remove any instances of `multiFactorUser.enrolledFactor`
+console.log(multiFactorUser.enrolledFactors);
+```
+
+# Firebase Dynamic Links
+
+⚠️ **REMOVED** ⚠️
 
 This package has been deprecated and removed from the React Native Firebase repository.
