Marraundrarensak,
Thank you for returning to the Apple Support Communities with this information. We can understand wanting to receive your notifications to both the iPhone and Apple Watch. We will do all we can to help you locate the answers you need.
As of right now, it sounds like the notifications are working as expected. Notifications go to either your Apple Watch or iPhone, but not both. To view this information and more, look here: Notifications on your Apple Watch.
If you need help with reviewing your Apple Watch Notification settings, you can look here: Change notification settings on Apple Watch. If you need help with reviewing your iPhone Notification settings, look here: Use notifications on your iPhone, iPad, and iPod touch.
We hope this information helps you out.
Cheers!
