Pairing with Edge and iPhone

Hi,

I have a couple of questions:

  1. Is it normal that my Edge 530 only shows the left pedal for connection (master/slave?) ? Should I see in sensors list both pedals?
  2. On Garmin connect app on my iPhone, it says that the 3.80 update is available. I do the update and both pedals flashes. But on the app, a "new" update, the 3.80, is always available. Like it's never updating the pedals. However, on my Edge 530, it says 3.80 ...
  3. My left pedal seems to be more free to turn than the right pedal. The right pedal has more resistance. Is it normal?

Thanks!
