No notifications on my iPhone after iOS 16.6 update

Hi MarNat80,

Thanks for contacting Apple Support Communities!

We understand that you don't see notifications for all apps since updating your iOS.

You may consider checking that you haven't scheduled a notification summary, which will schedule times for you to receive notifications and check that you don't have Focus enabled which can prevent notifications from coming through. This is a great resource which will show you how to manage notifications on your iPhone and check for a notification summary: Use notifications on your iPhone or iPad - Apple Support

"Schedule a notification summary

With iOS 15 and iPadOS 15 or later, you can schedule times to receive a summary of notifications each day so you can catch up when it's convenient for you. The summary is personalized to you and ordered by priority based on how you use your apps, with the most relevant notifications at the top.

To schedule a notification summary: 

1. Go to Settings > Notifications > Scheduled Summary, then turn on Scheduled Summary.
2. Under Apps in Summary, select the apps that you want to include in your notification summary.
3. Under Schedule, tap the Add button  to add a new schedule or the Remove button  to remove a schedule. Then adjust the time for each scheduled summary you have set up.

To add new apps to the summary, go back to Settings > Notifications > Scheduled Summary and select the apps under Apps in Summary. Each app appears with a number showing the average number of notifications that you receive each day from that app."

Focus will allow you to choose which notifications you'd like to see when you have Focus enabled as outlined here: Use Focus on your iPhone or iPad - Apple Support

Turn on Focus

1. Go to Settings > Focus. 
2. Tap a provided Focus option—like Do Not Disturb, Personal, Sleep, or Work—then tap Customize Focus.
3. Set up your Focus. You can select allowed or silenced notifications from people and apps, connect your Lock Screen or Home Screen, have this Focus turn on automatically, and add Focus filters.

You can also enable Time Sensitive notifications from apps, which allows apps not in your allowed list to send notifications marked as Time Sensitive.

You can also turn on Focus from Control Center. Just open Control Center on your iPhone, or on your iPad, touch and hold Focus, then select the Focus you want to turn on.

When you set a Focus, the icon appears in the status bar and on your Lock Screen, and your status is automatically displayed in the Messages app. When people try to send you a message, they'll see that you've silenced notifications, but they can still notify you if it's urgent.

When you use Focus on one device, the setting is automatically applied across your Apple devices that are signed in with the same Apple ID."

If you notice that notifications aren't working for a specific app and your settings are correct, you may consider contacting the app developer directly to help you to determine if there are settings within the app itself which manages your notifications. If you need help to locate an app developers contact information, this resource will help you: How to contact an app developer - Apple Support

"Contact the developer of an iOS, iPadOS, or watchOS app

1. Open the App Store on your iPhone or iPad.
2. Search for the app, then tap it. If you can't find it, tap the account button  or your photo at the top of the screen, tap Purchased, tap "Not on this [device]," then tap the app.
3. The app's product page appears. Scroll to the Ratings & Reviews section, then tap App Support. If you don't see App Support, make sure that you're signed in with the correct Apple ID."

We hope this helps you.

Take care!
