I get no notifications when my iPhone is in the lock mode

Hi MargoApple,

Please check out this link, which explains using notifications from the Lock Screen, and may be helpful: Use notifications on your iPhone or iPad

Open from the Lock Screen

You can see your recent notifications on the Lock Screen by picking up your iPhone or waking your iPad. You can also do these things from the Lock Screen:

* Tap a single notification to open the app that it's from.

* Tap a group of notifications to view all recent notifications from that app. 

* Swipe left over a notification to manage alerts for that app, or clear the notification.

* Touch and hold a notification to view the notification and perform quick actions if the app offers them.

To show the contents of notifications on the Lock Screen without unlocking your device, go to Settings > Notifications > Show Previews, and select Always.

In iOS 17 and later, you can also view notifications while your iPhone is in StandBy.

Thanks!
