Not sure if this has already been covered here but I found the "Activate on Wrist Raise" behavior not 100% reliable until I realized the algorithm is looking for the arm to be horizontal before doing the wrist turn towards you. If your forearm is at an angle it frequently doesn't trigger. So make sure your forearm is horizontal before you turn your wrist and it is 100% reliable. Takes about 10 minutes to refine this action and it becomes habit after that. Try it.
