If you're still using iOS 27.0.1, you should update to the current version, iOS 27.2.1. Then, delete the third party apps and re-install them. The first time you launch them again, you should be asked to give permissions, including for notifications.

If any Focus mode is enabled, notifications from certain apps may be delayed or suppressed, depending on your Focus settings. In some cases, you may not receive a notification until you manually open the app. Check whether a Focus mode is active and review its notification settings to ensure the app is allowed to send notifications.

Then please check the following.

1. Check your DND status - Settings > Focus [Do Not Disturb]; Use Focus on your iPhone, iPad, or iPod touch - Apple Support
2. Three primary factors trigger the automatic activation of the Focus modes. Users have the flexibility to deactivate each of these factors based on their individual preferences.
   1. Automatic Activation: Driving, Fitness, Gaming, Mindfulness
   2. Smart Activation: Work, Reading, DND
   3. Scheduled Activation: DND, Gaming, Mindfulness, Personal, Reading, Sleep, Work, Fitness
   4. Here are comprehensive explanations for each of these three triggers. --> Unveiling the Multi-Faceted Triggers of DND Automatic… - Apple Community
3. Check Bedtime Status - Clock App; Use Bedtime to track your sleep on your iPhone - Apple Support
4. Check your iPhone Sound Volume; Adjust the volume on your iPhone - Apple Support
5. Check Call Audio Routing; Call Audio Routing Bluetooth / Speaker / Automatic
6. Check Auto Answer Calls; Turn off Auto Answer Calls
7. Check the list of Blocked Numbers --> Block phone numbers, contacts, and emails on your iPhone ...

Notification Preview when Screen is Locked, Notification Alerts, Notification OFF, and much more...

1. To get Notifications when the Screen is locked see the pic below which is self-explanatory

2. To turn ON notifications selectively for apps, go to Settings > Notifications > Scroll Down to the App and turn ON notifications... Change notification settings on iPhone - Apple Support (IN)

3. Some apps have their own notification settings over and above the iOS notification settings: An example of Instagram Notification settings is given below

Not every issue an individual encounters on their device can be attributed to an iOS update. iOS 27 or later may have coincided with what you are experiencing, but that does not mean the issue was triggered by iOS. Coincidence in timing is not, by itself, evidence of causation.

If the update itself were the root cause, then every device running that same version of iOS would exhibit the identical problem. In such a scenario, the forums would be flooded with countless posts reporting the same malfunction, creating an unmistakable wave of complaints that no one could possibly overlook.

The absence of such widespread reports strongly indicates that the issue is not a general, system-wide problem with iOS 27 or later, but rather something specific to the individual device, its configuration, installed apps, settings, hardware, or another interacting factor.

In short: iOS 27 or later may be a coincidence in timing, but there is no basis to conclude that iOS itself triggered the problem simply because the issue appeared after the update.
