Somehow I have changed the vibration length of 1 app in the watch so it only vibrates ones shortly. I would like to change the vibration of other apps too to this. Particularly WhatsApp because once I get one text message, it vibrates for all of the messages I have received every time. So say I have 2 different chats that texted me twice, and a third person contacts me, I will receive 5 notifications of two buzzes.
How can I change the vibration length and is it possible to change settings so I receive just one buzz for new notifications (instead of it buzzing for every notification I received on the app)?
