Delay in notifications

This can confuse new Watch owners

Apart from actual phone calls which ring on both by default. Notifications for messages etc follow these rules…

• If the phone is in use (open) then you get notifications on the phone.
• If the phone is locked you get notifications on the Watch
• If you go into each notification type and use Custom and disallow notifications they go to the phone always and not to the Watch

Notifications on your Apple Watch - Apple Support

With Whatsapp and some third party "messenger" apps there is no companion app on the phone and notifications may be limited anyway, but the above rules should apply.

you said originally "...my notifications (whatsapp,messenger and imessage) are not coming through on my watch at the same time as to my phone..."

but notifications do not go to both Watch and Phone so I don't know where you experience the 30 seconds delay to be able to answer.

Watches generally respond slower to external messages than a comparable iphone , but where it matters, activity measurement, heart rate, timers etc they work in real time.

...meant to say because in most cases the notifications come to the Watch via the iphone.

Also I meant to say that the sound and haptic (ping) notifications go as described.

If you set phone notifications for lock screen or notification centre they will still show there but silently
