Instalé @react-native-firebase/admob

y luego usé pod install. cocoapods recibe un error. También usé pod install --repo-update, no funcionó para mí. este admob funciona muy bien en Android, pero iOS muestra este error. Si sabes cómo, te agradecería que me lo hicieras saber.

 [!] CocoaPods could not find compatible versions for pod "firebase/AdMob": In Podfile: RNFBAdMob (from `../node_modules/@react-native-firebase/admob`) was resolved to 11.5.0, which depends on Firebase/AdMob (= 8.4.0) None of your spec source contain a spec satisfying the dependency: `Firebase/AdMob (= 8.4.0)`.
