Late or Delayed Notifications on iPhone
In many cases, the problem of late or delayed Notifications on iPhone is usually related to the Wi-Fi/Cellular network being spotty and other network related problems.
However, this problem is also known to occur when the battery level on iPhone goes below 20%, which automatically enables Low Power Mode on iPhone.
In other cases, the problem appears to related to Scheduled Notification Summary option being enabled on iPhone, which can sometimes end up delaying notifications from certain Apps.

If you are not connected to Wi-Fi, take a look at top-left corner of the screen and make sure that the signal strength at your current location is good enough.
If the reception is poor, it confirms that the problem is due to poor network connectivity.
2. Enable Notifications for Apps
Make sure Notifications are allowed on your device for Messages, WhatsApp and other Apps from which you want to receive Notifications.
1. Go to Settings > Notifications > select the App from which you want to receive notifications.
2. On the next screen, make sure Allow Notifications option is turned ON (green).
Repeat above steps for other Apps from which you want to recieve Notifications.
3. Disable Low Power Mode

1. Go to Settings > Battery.
2. Disable Low Power Mode by moving the Slider to OFF position.
