Why aren't my haptic notifications working on Apple Watch?

Ive had my watch for a month and noticed that haptic notifications don’t always work.

• i don't have any active focus.
• notifications are turned on.
• silent mode is on
• haptics is on prominent

i have reset , unpair , pair , set as new watch my watch twice and still encounter the issue

anything else to consider?
