DevApp error "{ionic-plugin-name} plugin not installed" in command console, but works in browser and emulator

Hi,

I’m writing a Ionic App that uses several plugins (example Geolocation, which are supported by DevApp - https://ionicframework.com/docs/appflow/devapp#native-cordova-plugin-support).

Testing via the browser works fine.
Testing via Emulator also works fine.

When I test the app via DevApp, the ionic console is logging that the plugins are not installed.

Anyone know how to resolve this?
