No Incoming Calls on Apple Watch
The reason why we’re recommending the thread above is that the discussion is similar to the issue that you are experiencing. The information in the thread also allows us to move our troubleshooting efforts towards a resolution by helping to resolve the issue you initially reached out to the community about, which is not receiving notifications when it comes to incoming calls on your Apple Watch.
Also, please remember that by default, the notification settings for the apps on an Apple Watch that you set up for yourself mirror the settings on your iPhone. But you can customize how some apps display notifications.
