IOS 12.1.4 update no longer allows WYZE (IOS) to access camera to read QR code

Has anyone else experienced the same issue with the latest Apple IOS update.

Go to setup a new camera.
Access the WiFi network
Waiting for the IOS device camera to read the QR code - and it appears that the WYZE setup app can no longer access the IOS device camera to try and capture/read the QR code?

Tried on several iPhone(*s), iPad(s) with no success. Unfortunately all are updated to 12.1.4

~1 week new WYZE cam user. Version iOS on iPhone is 12.1.4(16D57). No issues with cam set up.

Reinstalled app. - now working again.
