In order to give the app access to the camera with an Iphone, do the following:
1. Open the app.
2. The first time you open the app it will automatically ask you to grant camera access:
/msdyn_blobfile/$value)
3. If you should for some reason fail to grant access to camera the first time you open the app you will instead need to do it through the settings on the phone. Find the app within your settings and turn on the camera access from there:
/msdyn_blobfile/$value)
4. Go back to the app. You are now ready to scan!
