No alerts on Apple Watch

Ensure conditions for notifications to appear on your Apple Watch are met

Please check to see if the following conditions are met for notifications to appear on your Apple Watch:

1. Notifications go to either your Apple Watch or iPhone, but not both. This is an iOS/watchOS behavior. For notifications to appear on your Watch, your iPhone needs to be locked or asleep, and your Apple Watch unlocked and on your wrist. You can find out more about where iOS/watchOS decides to deliver notifications in Apple's support document. 
2. There are other situations that will cause notifications to not appear on your Apple Watch:
   1. When your Apple Watch is disconnected from your iPhone, your notifications go to your iPhone instead of your Apple Watch.
      
      To verify that your Apple Watch is connected to your iPhone, swipe up on the watch face to open Control Center. If your devices are disconnected, you might see the red iPhone icon , the red X icon , or the Wi-Fi icon . Check that the green iPhone icon is present:
      
      
      
      
   2. When your Apple Watch locks or you turn on Do Not Disturb, your notifications go to your iPhone.
      1. When your Apple Watch is locked, the lock icon  appears on the watch face
      2. When Do Not Disturb is on, the Do Not Disturb icon  appears on the watch face.
