I recently replaced my phone. I tried pairing my multisport watch to the new phone (galaxy 9+, in case that matters) and the watch is telling me I need to go to "manage" in the app and disconnect it from my last phone. There isn't anywhere in "manage" to do that, at least that I can find. I've already sent the old phone back as part of my trade in deal. How do I disconnect my watch from the last phone so I can pair it with the new one?
