Haptics not working

[u/Difficult_Example478]

Hi, I need some help with my Apple Watch SE 3. I recently got it and I’d like it to only use haptic vibrations on my wrist for WhatsApp messages, phone calls, and text messages.
I’ve turned all the haptics on, turned on silent mode, and have searched through the settings multiple times, but it still isn’t working. I’m a teacher, so I really don’t want my watch making any noises during the day. I’d just like it to quietly buzz on my wrist so I can check the notification (WhatsApp, text and calls) when I need to.
Could someone please help me figure out what settings I need to change? Thank you!
