App behavior difference between native and ionic view

Hi

I bought https://market.ionic.io/starters/ionic-starter-messenger

I upload it on a test app.

Through ionic view it’s perfect.

When I build it to a native app, it’s near from perfect but some behavior are strange.

Per exemple, when clicking on a input field that bring the keyboard, the input field doesnt go up and stay behind the keyword.

Any ideas why the behavior is different ?

Thanks
