Ionic + Blackberry Dynamics = live deploy does not work

Hello Forum,

i have a combination of an ionic app with the Blackberry Dynamics SDK. When i use the ionic live deploy feature the app does not refresh to the new version.
The same app refreshes to the new version when i use the ionic view app. On the blackberry device however it does not refresh.

Have i been missing something?
