AdMob rewarded ad does not show on iOS

[lachtos]

Issue

On iOS only, calling .show() does not display the loaded rewarded ad.
Android works fine.
I have the same behaviour when using react-native-admob@2.0.0-beta.5 but on expo-ads-admob@5.0.1 it works great.

Using react-native-firebase@5.5.3, same behaviour on 5.4.3 also.

In Xcode I'm getting this warning:
2019-06-25 22:47:41.709477+0300 AppName[11144:66747] Warning: Attempt to present <GADFullScreenAdViewController: 0x7fb0a6fa7010> on <UIViewController: 0x7fb0a4f21630> which is already presenting <RCTModalHostViewController: 0x7fb0a817f650>

what version of react-native-firebase are you using? what version of react-native-admob and expo-ads-admob did you try?

[lachtos]

Editted the issue, but I am using the latest releases. Was the same with firebase 5.4.3 though.

[mikehardy]

Thanks - that should be useful, knowing you’ve got one of the three that’s working (with a version) can hopefully let us check exactly what they are doing differently

This seems like a react-native bug and is being worked on as far as I can see from the thread above. I was using niftylettuce/react-native-loading-spinner-overlay but will be moving to a custom solution because of this interaction. I guess expo has a custom solution for this so their ads show without problems..

Since it's not really a bug in rn-firebase, I'm closing the issue
