Your watch can only remind you of notifications that are displayed on the status bar. In this case, ensure that you have enabled notifications to be displayed in the status bar. Perform the following:
For Android users (taking EMUI 9.0 as an example): Go to Settings > Notifications, select apps you want to receive notifications from, enable Allow notifications and Display in status bar, Banners, and set Lock screen notifications to Show.
For iOS users: Go to Settings > Notifications, select apps you want to receive notifications from, enable Allow Notifications and Notification Center. Follow settings in your Message app to configure settings in WhatsApp and other third-party social media apps.
If messages from your Whatsapp still cannot be displayed, open Whatsapp, go to Me > Settings > Notifications, and enable Notifications Center, and check whether this issue can be resolved.
If the issue persists, restart your phone and connect your phone to the watch, and try to see whether you can receive notifications on your watch.
If you connect your watch to a phone running iOS 11.0 or later, go to Settings > Notifications. Touch the app for which you want to receive notifications and enable Show in History.
Restart your phone if you still encounter this issue after connecting your wearable device to other Android phones and adding the NoiseFit Assist to the protected background app list. If this issue still cannot be solved, this is an issue caused by your phone's manufacturer. The NoiseFit Assist is not an app developed by those manufactures, so it will be cleared from the background app list when the phone's power consumption is high.
