Q: Not Getting Haptic feedback in apple watch for whatsapp messages

Hi

It may help to restart both your iPhone and your watch, turning both off together, then restarting your iPhone first:

• Restart your iPhone, iPad, or iPod touch - Apple Support
• Restart your Apple Watch - Apple Support

If the issue persists, I suggest that you contact the developer of WhatsApp Messenger, explaining that the issue arose in connection with their recent app update:

• Email: support@whatsapp.com

In that case, as previously advised, I suggest that you contact the app developer for assistance.
