Hey same here also with a Redmi note 9 pro, MIUI 14.0.5 and android 12SKQ 1.211019.001.

I have an update. I chatted with Suunto, but they were not very helpful to be honest. Said will review the logs and discuss it with the team. But if issues persisted to send the watch back so they can check it. I did a factory reset and did not work either. I then reverted to the previous SW version and apparently that made it work. Granted it has been only one swim, but there were 0 issues with the laps.

It is normal i have to reset every 2 to 4 days my phone just because a part of the Communication between watch and phone is not anymore working? And the Information (Sync with Suunto App) why sometimes it takes hours to go away, what information need so long to travel. the phone is normaly not more then 1 to 5m away ?

I would very much like to disable VO2max detection for trail running activities too. When I owned Garmin, my VO2max continuously declining because a do at least 1-2 serious trail runs per week on a steep terrain. Once I disabled trail running VO2max on Garmin, the estimate steadily went up from 47 to over 52 in just a few months. Now, that I have owned Suunto Race S and S for over a year, my VO2max has been stuck in the 48-49 range, occasionally going to upper 49. I feel that is a bit too low. Every time I do a trail run, it always goes down to lower 48 or even upper 47. The funny thing is that I am a relatively better trail runner than I am a road runner. I have good and efficient technique when running on technical trails, but despite that the VO2max estimate is always punished!

@cdfreet After a few weeks of testing, the issue started to occur again. The OHR sensor turns off without warning and does not turn back on until the watch is removed from the wrist or a forced restart is performed. [image: 1766697067740-img_5821.jpeg]

Está claro que esto es un fallo recurrente. A mí Sunnto Run con el que llevo algo más de una semana le pasa lo mismo. De 9 días he recibido el informe matinal 3 veces

@Brad_Olwin @SuperFlo75 Thanks, I’ll wait for the update and hope it solves the issue
