Haptic feedback different depending on app

Hello everyone,

Something that have been bothering me for quite a while, taptic engine is working fine though the feeling is different depending on the apps sending notifications.

Using Apple stock apps i sense this soft tap-like feeling on my wrist, which is perfectly fine, but for third party apps i only feel an iphone-like vibration (classic buzz, not soft tap)

Is this a normal behaviour or should third party app vibrations works the same as stock ones ?

Thanks

Thomas
