iPhone 16 Max camera not scanning QR codes within authenticator apps

“When I press the button to scan the QR code - all i get is a blank screen - i cant scan the QR code in first place - usually it can be seen on the screen to scan - but its a blank screen as though the camera hasn't activated. even though in the settings it has permission.[…]“

Ah!

Successfully Deleting a Shortcut on an iPhone:

A. Close All Apps:

The camera app may be stalled. I get this error, but only intermittent and rarely. So save what need be and then close all apps. Hold you finger down as you swipe up from the bottom-left corner of your screen. Then, close all of these open apps, by swiping up quickly for all apps.

B. Perform a Force Restart:

Try Force Restarting your iPhone. Save any information that need be. Then perform the Force Restart. See if you can then perform those, no longer getting the blank screen. Go Here: Force Restart iPhone - Apple Support

Connecting through QR code:

If someone is providing access to it through a QR code, then open the Camera app and take a photo of it, when it is framed in the corner with perpendicular yellow lines. Then, open it in the Photos app.

Thanks

“Unfortunately - its while using the apps - they need to scan QR codes to add new keys for the 2 factor identification. Using the normal camera app to scan the QR code - the scan doesn't link to the app i want. i.e the scan has to be done within these authenticator apps.”
