### How to reproduce these conditions

**Failing test unit, Stackblitz demonstrating the problem**

**Steps to set up and reproduce**
It was working previously at @angular/fire 6 with firebase 8.
After upgrading to the latest version, there's totally no data showing up on iOS.
But it was just fine on Android and Web.

I had set iosScheme to ionic, will it be the problem?
If not unable to launch ionic app after upgrade to angular/fire 7 + firebase 9.

**Sample data and security rules**

### Debug output

** Errors in the JavaScript console **

** Output from `firebase.database().enableLogging(true);` **

** Screenshots **

### Expected behavior

### Actual behavior

未提供原始檔案、失敗的測試、StackBlitz 重現、偵錯輸出、螢幕擷取畫面、預期行為或實際行為。請先在 iOS 上重現從使用 Firebase 8 的 @angular/fire 6 升級至使用 Firebase 9.6.10 的 AngularFire 7.3.0，並比較 Android 與 Web。完成的標準是 iOS 應用程式顯示預期資料，且已確認原因或所需的相容性變更。
