      @thailon, well, for me the watch behaviour has changed: it sounds strange, illogical, but, currently, great sleep tracking.

      I’ll keep you up to date!🤞

        have you sent logs to Suunto, each time it has happened?

        I have sent logs to Suunto, more or less each time it has happened, but…

        How does this help Suunto to troubleshoot the problem if I am not able to tell to Suunto what was my problem? Maybe an app update introducing the possibility to highlight the problem will be useful…

        Now, as read here on the forum, I have to sent logs and then search, here, for someone “inside” Suunto and tell her/him what was the problem. Not very efficient…😅

          @Matúš maybe I could try to change screen from that last one (which I used always) to another one 🙂

            Hi together,
            I think with the latest update to 3.39.20 the bug is back.
            Yesterday, soft reset helped to reactivate Heart Rate sensor, after today’s “4-hours sleep” (it stopped working again in the middle of the night) I have to do another one…
            Somebody seeing the same device behavior?
            Kind regards:)

                No problems since the last update. OHR, sleep tracking and heart rate variability are working without any issues.

                  Same here after the Softwareupdate!😢 This Morning HR and Ox stopped to work during the night. Sleep tracking stopped too.
                  Watch enters Sleep / do not disturb mode at 23:00. Measurement seemed to stop at around 2:45, when the OX Sensor seemed to do its last measurement. OX Sayed last measured 5 hours ago when I realized it around 7:50. So I guess there is a coincidence between HR sensor and ox sensor.

                  Will try to turn of OX sensor if it happens again.
                  Couldn’t reproduce while starting OX measuring manually.

                  Didn’t have this issue for quite a long time.

                        I’ve also had the same problem with HR Measurement stops since last update. Soft reset helps only for couple of hours, then it stops again.
                        Any recommendation how to solve the problem?

                            @Ludwig-Pichlbauer I can confirm the bug is back with 2.39.20.
                            No measurement of heart rate after a random period of time, I just discover it when I need it and a soft reset is required in order to restore the heart rate detection.
                            Very annoying, particularly because it’s a recurring problem

                              @Sergio-Nasi as written above this is currently being worked on by Suunto.

                              What helped me with other firmwares when OHR was jammed: start a manual SpO2 measurement. Maybe you want to try instead of resetting the whole watch?

                                  Same problem for my Suunto after the last update, some days ago. Reset and manufacturing settings do not solve the problem. The update is 2.39.20

                                    @Egika It doesn’t work. Despite starting the measurement manualy the leds doesn’t start flickering. Thanks anyway.

                                          Same for me. Switching of my peak pro and starting it again reactivates the lights for measurements again but after around 4-6 hours it’s stops again. Manual measurement not switching on lights anymore.
