iOS Error: Compiling react-native-maps Pods/react-native-google-maps - AIRGoogleMapPolylineManager.m

Yes - I use that. So currently there is no way to operate both at the same time?

Using a newer react-native-maps version supporting the property throws another error:

[!] CocoaPods could not find compatible versions for pod "react-native-google-maps":
  In Podfile:
    react-native-google-maps (from `/Users/expo/workingdir/build/node_modules/react-native-maps`)
Specs satisfying the `react-native-google-maps (from `/Users/expo/workingdir/build/node_modules/react-native-maps`)` dependency were found, but they required a higher minimum deployment target.
Error: Compatible versions of some pods could not be resolved.
You are seeing this error because either:
  - Versions in the cached Podfile.lock do not match required values in Podspecs of some installed libraries. To fix this, you can re-run build command with "--clear-cache" option, or select "Clear cache and retry build" on the build page.
  - Some of the pods used in your project depend on different versions of the same pod. See logs for more information.
