How to receive WhatsApp notifications on Apple Watch:
What we must do is go to the app of the Watch we have installed on the iPhone . Once here, on the main screen, click on the "Notifications" tab . We slide to the bottom and we will see all the applications that we have installed.
On the one hand we will see the apps that are available for WatchOS and on the other, the applications from which we can receive a notification duplicate of those we receive on the iPhone . In this case and in this section, we find the app of WhatsApp .
It is likely that if we do not receive notifications on the clock, it is because we do not have this tab activated. When we first set up the watch, it asks us if we want to receive a duplicate of iPhone notifications on the Watch . In the event that we say no, be it due to ignorance or because we simply do not want notifications, this section is the one that we must activate.
You should also check WhatsApp notifications on the iPhone , in Settings / Notifications . In it you must have activated "allow notifications" , unless the notice on Locked screen, Notification Center and / or strips . We advise you to activate, above all, the Locked screen .
Also, within the application settings we must activate the display of message and group notifications, in addition to activating the app notifications, for example, activating "Strips" . Now every time we receive a message, we will receive it on the watch and we can also reply . A good way to save battery life on your iPhone and to reply more urgently to the most important messages.
