For those of you who pair a Bluetooth heart rate chest strap to Apple Watch have you experienced any trouble with it being recognized/paired every once in a while? I have experienced that twice in the last two weeks I have started using the chest strap once where it wouldn't automatically pair after turning it on (the chest strap) and today during a dedicated workout mid-way it totally lost connection to the watch. In both instances I thought that the chest strap is to blame but when I look over my Bluetooth settings on the iPhone the HRM shows up just fine so it's not a problem of it not turning on. Only after restarting the Apple Watch do I get the HRM recognized again. Anyone has had similar experiences or maybe mine is defective in that regard?
