This privacy setting the phone's camera is to prevent an app accessing the camera without your knowledge.
So......
In IOS Go to:
Preferences
Privacy
Camera (I don't use either, but these apps may also need access to the photos app)
Locate the programs that are not allowing access to the camera and enable access. (flagged green)
The same is for the photos following the same steps just replace "photos" for "camera" in the steps.
