You’re right. The toggle isn’t there for CamPlus. I only have one camera running CamPlus and hadn’t noticed the differences in the screens.
Here is another link about the same problem:
Some additional thoughts:
What phone OS version and App version?
Which firmware version on the camera?
Try clearing cache on the phone, logout, login, reboot phone.
You can try removing CamPlus from the camera and re-apply it.
Last choice, delete the camera and re-add to your account.
