How to mirror Apple Watch 8 with iPhone 13 Pro
My watch taps me but the phone doesn't make alert. It's hard to feel that tap if I'm in motion so I miss alerts.
Notifications appear on your Apple Watch or iPhone, but not both. If your iPhone screen is off and you are wearing Apple Watch, your watch notifies you. If your iPhone is on, your iPhone alerts you. You cannot get a notification on both devices at the same time. This is by design.

You may be helped if you go into the Apple Watch on your iPhone and in Settings > Sounds & Haptics, turn Haptics to Prominent and increase the volume, which will make the haptic very difficult to miss.
