I have an AW Series 3 and an iPhone 7 Plus. I use Siri every so often and always wonder how Apple decides which Siri on which device will answer my request. Many times when I call on Siri, I see both my phone and watch start to respond but one of the devices gives up and the other takes over. Today, I asked Siri to remind me to do something today and both my watch and iPhone responded as Siri would. I looked into my reminders and there was two of the exact same reminder. Anyone else have this happen?
