Hello Mossi_z,
Thanks for choosing the Apple Support Communities. If notifications aren't expanding properly, let's see if these steps will help resolve the issue.
Use notifications on your iPhone, iPad, and iPod touch - Apple Support
"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.
Change group notification settings
- Go to Settings and tap Notifications.
- Select an app and tap Notification Grouping.
- Select one of these options:
- Automatic: The notifications from the app are grouped according to organizing criteria within the app, such as by topic or thread.
- By App: All the notifications from the app are grouped together.
- Off: Turn off grouping."
We hope this helps.
Cheers!
