Ionic io view shows blank white screen

I have uploaded my app using ionic upload after logging in. seems to work ok. and have the ionic view app on my phone (android) and i see the app listed and updated on my phone but when i select it i only see a blank white screen after that.

on the pc using browser the app works ok. Am i missing a step someplace. Do i need to build for android/ios before uploading, actually tried that but no luck either.

There are no errors etc. that I can see. How can I find out whats going on. The application id i 0c84d792

I had a similar problem a couple of days ago and this blog post helped me.
All I had to do was adding a plugin:

ionic plugin add https://github.com/apache/cordova-plugin-whitelist

Special note: This is just a work around – this is projected to be ‘fixed’ in the very near future…
