UWP AR Vuforia App Camera Turning Off when Minimised and not Turning Back On

Hey,

I am currently developing an AR application with Vuforia. 7.2 and Unity 2018.1.0f2 for UWP. When building and running the application on a Surface 3 or Desktop with a webcam the application works as expected until the application is minimised.

From what I know about developing for UWP when application is minimised its put into a suspended state and Windows turns of any devices used by the application i.e. the camera however whenever I put the application back into focus the camera does not turn on again so my application carries on running but the video feed from the camera is frozen and not updated.

I was just wondering if anyone else has experienced this issue?
