      Everything works here, I’ll have to keep an eye on it.

        @Anrich-Potgieter Same here.
        I use an HRMstrap when running, but not on the Rowingmachine.

          Same here, first activity with new firmware. First 11 minutes of OHR reading is incorrect. I had same pace from begining on closed lap. My HR was higher from beggining. Between 30-40min lower HR is fine as i went slower in that part.

          But i experienced something like that rarely with old firmware too.

            Came here to see if anyone else was seeing this. Had a few workouts and suspected this but on a new programming and 2nd guessing. Today, I wore this and bicep strap with AmazFit app sync. WILDLY different results for the first 10 mins or so.

            First 3 mins or so is a warmup and expected the lower rates there, but after an initial spike, you see the strap lock on at least 5 mins sooner to my cadence.

              I have a similarly suspicious HR output from a pool swim yesterday.

                Another two workouts with very broken HR, the HR is locked until my first rest, then begins to climb.

                  @Anrich-Potgieter Ok. I did a repeat of the same workout with the Vert 2 instead of my Race 2 and was back within normal ranges of the bicep strap. Not sure if this is something just with the Race 2 update as they supposedly share the same sensors. I’ll keep testing.

                      I have a similar problem with my Race and Polar H10, where it gets stuck at 70-80bpm sometimes.

                        I had the same issue yesterday and today the heart monitor stopped working. After a hard reset, the HM came back and it is not working
