Unable to take a picture of a document or take a selfie

My phone won't allow me to take a picture of my documents

In order to take a picture of your ID document for verification you will need to give the App access to your camera.

If you see a 'Loading Camera' message on your phone screen and a updating circle you will need to go to your phone settings to allow camera.

Below is a screenshot showing the message you may see on your phone. 

Permissions on an iPhone can be changed by moving the 'camera' toggle to the right, so it's green.
