### 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

未提供源文件、失败的测试、StackBlitz 复现、调试输出、屏幕截图、预期行为或实际行为。首先在 iOS 上复现从使用 Firebase 8 的 @angular/fire 6 升级到使用 Firebase 9.6.10 的 AngularFire 7.3.0，并对比 Android 和 Web。完成的标准是 iOS 应用显示预期数据，并确认原因或所需的兼容性变更。
