I just bought the Garmin HRM-dual strap. It will connect to my vivio active 3 but then disconnect seconds later. I’m wearing the strap. I turned the wrist monitoring off so I can tell just by looking at the watch if it’s connected or not. I’ll connect it through the settings ->apps and accessories, it will connect. But when I go back to the main screen, it’ll show the hr for a few seconds and then disappear. If I go try to connect it again, it connects, only to disconnect again moments later. Any thoughts?
