Not sure if this is happening to anyone else but ever since the previous update came out when I start a cycling workout the HRM picks up my HR but after a couple of minutes it craps out. Then 10-15 minutes later it comes back and is solid the rest of the workout. This has happened 4 straight times. I was hoping the latest update would fix it but I did a ride today and same thing. So now 5 in row. I haven't tried any other workout to see if the issue is across the board, that will be my next test.
