camera permission

Settings->Privacy->Camera->Walmart and make sure its allowed.

If its not there, then it means the Walmart app has not requested access to the Camera yet.

This could be in two different places in the Settings app.

If it is the Walmart app requesting access to your camera then you should find that at Settings > Privacy > Camera.

if it is the Walmart website in safari requesting access to your camera then it would be in Settings > Safari > Camera.

You're welcome.
