Same problem here. isMultitaskingCameraAccessSupported is returning false. I was also trying to add 'com.apple.developer.avfoundation.multitasking-camera-access' entitlement, but an error appears saying - Provisioning profile "iOS Team Provisioning Profile: " doesn't include the com.apple.developer.avfoundation.multitasking-camera-access entitlement.
