Suunto 9 Peak Pro HR Sensor Issues After Software Update (v2.39.20)
Yes, known issue with the latest firmware update for the 9PP. They're working on it. The current workaround is to downgrade to a prior firmware version: https://forum.suunto.com/post/159509

Suunto Run or 9 Peak Pro?
The Peak is an outdated model with ancient technology. As a longtime Suunto user, I honestly couldn't recommend the 9 Peak Pro to anyone with good intentions.

Issues with Sleep Tracking
My old peak pro couldn't register awake times. I'm a restless sleeper and I get up a lot at night. Suunto frequently registered it as 0min awake. If it can't pick up periods of wakefulness, the data is not directionally correct IMO

Swimming
Swimming is hard on any HR tracking watch. Best practice is watch should be well clear of the wrist joint, an inch up and well fitted - snug, not lose, but comfortable, enough. Those resolved the off HR data your seeing for me with my 9PP.

Optical Heart rate way off after update
Yes, the same. Suunto 9 Peak Pro. After update HR sensor is completely off. The same oxygen sensor. The issue is not solved by Reboot/reset

Sleep track
I have 4 days (and nights) with my Suunto Pro Peak 9 and I have not gotten yet the sleep stages. Is there something I am doing wrong, or does the watch need more nights to collect enough data?

Curious About Extremely High HR While Hiking
It was extremely hard. It also wasn't a watch, it was Airpods pro 3. But it lines up with Garmin, Suunto, and Apple Watch for what I expect my HR to be based on how hard I'm pushing. I ignored my watch because it was sat at 95 for all of the uphill and half of the downhill. The second half of the do

Suunto run
I love the idea of a simpler watch on the level of a Forerunner 165, but Suunto should try to differentiate itself in this space better. This battery life is worse than the 9PP for instance. The AMOLED screen is a mistake. Go the opposite direction with an always on e-ink color screen that will exte
