I think my reply was not at the post I wanted. So, I succeded to receive notifications from WhatsApp by going on the phone in Galaxy Wereable - Settings - Notifications. Put On at the Notifications and select the Apps you want to receive notifications on the watch. You should have also the notifications aloud in your phone. After that I restarted the watch (didn't receive any notification until restarting the watch). Now I receive notifications from WhatsApp. I can see the message I did not read on the phone. I can answer from watch. I can not see pictures or videos on the watch if the message has these attachments. After I read the notifications on the watch, are not on the watch anymore. You don't have access on the apps like in the phone.
