I've had some frustration using Siri on my Watch as I drive out of my neighborhood, where the cell signal is relatively weak. Siri just won't take my dictation. In that same area, however, Siri will work just fine on my iPhone. Is there a setting I can adjust to improve this, or is it merely a fact of life, that the bluetooth connection between the watch and the phone degrades the cell connection just enough to render Siri unusable in those weak cell areas?
