      @Brad_Olwin Good week
      Now that we are “after the holidays”
      Do you know if there is any news regarding an update for all the watches “affected” in the last update

        For what it’s worth- same here - watch auto updated to 2.39.20 in Dec & since then, all sensors stop (heart rate, oxygen, sleep) frequently- definitely overnight but possibly more frequently than that… all ok after a restart but come on Suunto, you’re better than this!!
        Have been using Suunto products for years & trusted my life in them diving which is why I went with Suunto for fitness watch but starting to regret it again - this looks like a bug reintroduced, really Suunto? This is software change management 101?!

          I’ve had this happen to me several times and it’s only solved by restarting the watch. 😞
          I hope they solve it with the next update.

              I am having the same problem. I’ve had to restart my watch to get the HR working. My problem - is that I do not have to option under Settings to revert back to the last update. Under Settings - General - I only have About, Software update, Time/Date, Language, Tones, Display, Power saving, Personal, Reset Settings, Power Off. I don’t have Data Privacy as an option. What can I do?

                @michmccoy same here. Watch is 6 days old. This morning no record of sleep. Not through the day. I read a shutdown and restart of the watch fixes it. Can confirm it does. Assuming it will go for another 6 days and stop again.

                  SPP9: Has anyone already tested the update version 2.39.34.22544 with regard to the heart rate problems described above?
                  I would like to read your experiences first 😉

                        @claenn I just followed arkaitgavan’s instructions to change the software and I selected the 2.39.34. That was the only other option for software. The previous software was 2.39.20. I was having the same issues with the watch not measuring sleep and not measuring heartrate without a soft reset at least once per day. Fingers crossed. Stay tuned

                          Just to add, I am having the same issue of the optical HR sensor crashing with my Race S (2.39.20). 2.39.34 is not yet available for this watch. Thanks @arkaitzgalvan for the instructions on how to go back to the previous firmware as it didn’t happen before the update.

                            @Aynrnd , as said in the Suunto app the new version is a downgrade to a previous version of the software to fix a critical issue caused by the latest update. This software is practically the same version as 2.37.48.
                            If your 9PP was fine before, It should be fine now.
                            Good luck!

                                I had similar problem with with my 9PP running software version 2.48.16 and now after the upgrade to version 2.50.28 still: out of the blue the heart rate monitor LED lights stop working. Only after switching the watch off and on again, it reactivates. I want to track my sleep and HRV and the failure happens most often at night messing up the statistics.

                                Anyone knows a sustainable solution? Much appreciated.

                                    I also have the same issue. 9pp running 2.50.28 and many times over the last year or more wrist heart rate stops. Green leds not flashing. Turn off turn on to fix but you only realise it’s stopped when you synch in the morning.

                                    Night sleep, recovery all inaccurate.

                                    I have no good reason to buy Suunto again ☹️
