Hey Debs1066,
Welcome to Apple Support Communities. It sounds like you have made sure that notification settings are correct. If everything looks good using the guidance from Notifications on your Apple Watch - Apple Support and other notifications are working OK, this may be an issue with the app.
Try deleting the app and redownloading it which may refresh settings. You can do that from your Apple Watch or iPhone. Steps below are the Apple Watch steps from Delete apps from your Apple Watch - Apple Support.
"How to remove apps from your Apple Watch Home Screen
- Press the Digital Crown to see all of your apps on the Home Screen.
- Touch and hold any app until the View Options screen appears.
- Tap Edit Apps.
- Tap the delete button
on the app you want to remove, then tap Delete App to confirm. - Press the Digital Crown to finish."
After that, reinstall the app and test to see if you receive notifications. If the same issue occurs, it may be best to reach out to the developers for further help. Reference How to contact an app developer - Apple Support for help finding contact information if needed.
All the best.
