Ionic 4 brings in support for multiple platforms (angular / react / vue). You need to import plugins such as the in-app-browser specifying which type you want in the import (e.g for angular `import { InAppBrowser } from '@ionic-native/in-app-browser/ngx'
Well this is embarrassing... I messed up the import, sorry about that.
