Whatsapp Group notifications are not showing in iwatch 3

Hi there saurav146,

Thank you for using Apple Support Communities!

It sounds as though you’re not seeing notifications for an app on your Apple Watch. You’re in the right place, we’d be glad to assist in seeking a solution.

Below is a resource that can help:

Notifications on your Apple Watch

This resource provides great information on Notifications on Apple Watch, we’d advise checking out the “Customize your notification settings” section to verify notification settings are set for the app. The “If you don't see notifications on your Apple Watch” section includes useful information as well.

If the issue still occurs after checking out that resource, we’d advise verifying all software is up to date on your iPhone and Apple Watch:

Update your iPhone, iPad, or iPod touch

Update your Apple Watch

And check for any software updates to the app:

Update apps or use automatic downloads

We hope this helps,

Cheers!
