Hello RMathewson,
Thanks for posting in the Apple Support Communities. We're happy to look into this with you. The way your Apple Watch receives notifications is based on your settings. Do you have your notifications set up to mirror your iPhone or have you customized them? You can review full details about Apple Watch notifications here: Notifications on your Apple Watch - Apple Support
Customize your Apple Watch notification settings
1. Open the Apple Watch app on your iPhone, then tap the My Watch tab.
2. Tap Notifications.
3. Tap an app to see its options. To use the same notification settings on apps that appear on both your Apple Watch and iPhone, tap Mirror my iPhone. Some apps allow you to customize your notifications. Tap Custom, then choose an option:
- Allow Notifications: Notifications appear in Notification Center and your Apple Watch alerts you.
- Send to Notification Center: Notifications are sent directly to Notification Center without your Apple Watch alerting you.
- Notifications Off: The app sends no notifications.
4. If you customize an app's notifications, you can also group notifications from that app. Tap Notification grouping, then choose an option: Off, Automatically, or By App.
Some apps offer further customization, while others only let you turn off Apple Watch notifications completely. Scroll down to the Mirror iPhone Alerts From section and turn off the setting next to the app.
If you have selected to mirror your iPhone, you might want to try customizing notifications to see if that helps with this unwanted notification.
Best regards.
