Text message notifications

Hello RSS_15,

Thank you for reaching out to Apple Support Communities, and we'll be happy to help in any way we can. We understand you're having issues with getting notifications for text messages since updating. To start, be sure the steps here are followed: Use notifications on your iPhone, iPad, and iPod touch - Apple Support

Also, check or change your notification settings as outlined here if needed: Change notification settings on iPhone

"Change notification settings

Most notification settings can be customized for each app. You can turn app notifications on or off, have notifications play a sound, choose how and where you want app notifications to appear when your device is unlocked, and more.

1. Go to Settings  > Notifications.
2. To schedule a notifications summary, tap Scheduled Summary, then turn on Scheduled Summary.
3. Select the apps you want notifications for in your summary, set a time for delivery of your summary, then tap  at the top left. (See schedule a notifications summary.)
4. To choose when you want most notification previews to appear, tap Show Previews, select an option—Always, When Unlocked, or Never—then tap  at the top left.
5. Previews can include things like text (from Messages and Mail) and invitation details (from Calendar). You can override this setting for individual apps.
6. Tap an app below Notification Style, then turn Allow Notifications on or off.
7. If you turn on Allow Notifications, choose when you want the notifications delivered—immediately or in the scheduled notifications summary—and turn Time Sensitive Notifications on or off.
8. For many apps, you can also set a notification banner style and turn sounds and badges on or off.
9. Tap Notification Grouping, then choose how you want the notifications grouped:

• 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.

To turn off notifications selectively for apps, go to Settings > Notifications > Siri Suggestions, then turn off any app.

When you use Focus, it delays the delivery of notifications on iPhone to prevent interruptions. You can schedule a time to receive a summary of the notifications you missed. See Schedule a notification summary."

We hope this helps.

Cheers!
