Lock Screen removed after iOS update.

Hello not_Sauer,

Thanks for posting in the Apple Support Communities.

It sounds like you've noticed that your Lock Screens may have disappeared after an update, right?

If that's correct, let's check if the Lock Screens are still saved with the steps below. The following resource will also include additional details on adding new Lock Screens, so check out any new features with this: Personalize your iPhone Lock Screen - Apple Support

Switch between Lock Screens

You can create multiple custom Lock Screens and switch between them throughout the day. If a Lock Screen links to a specific Focus, switching from that Lock Screen to another also switches your Focus.

1. Touch and hold the Lock Screen until the Customize button appears at the bottom of the screen.

2. Swipe to the Lock Screen you want to use, then tap it.

We hope that's able to help with locating your Lock Screens, or setting up new ones.

Have a great day!
