In case anyone is stuck with this and until the different issues are fixed, I made a little guide on how to use yarn workspaces with Create React App and Create React Native App (Expo) to share common code across. Hope you find it handy! ~~https://learn.viewsdx.com/how-to-use-yarn-workspaces-with-create-react-app-and-create-react-native-app-expo-to-share-common-ea27bc4bad62~~ https://medium.com/viewsdx/how-to-use-yarn-workspaces-with-create-react-app-and-create-react-native-app-expo-to-share-common-ea27bc4bad62
