I have the same issue, since friday. I make the update thursday : 2.40.38 on race S. HR measures stopped twice around 10-20 minutes until I restart each times. Yesterday, exactly the same : it stopped around 15-20, i don’t restart. I decided to reset, yesterday… This morning, my watch crash I start, twice a cycling activity. On the third attempt, it was entering “safe mode”. It work fine and same problem, HR crash…

@Ghost often yes, but you can’t blame the user when an app is not generating graphs, can you?

@Mff73 This is what I do as well. Issue is pretty easy to reproduce, and I have been dealing with it for a couple of years now. Fortunately, updates are not too often… I would expect the fix is easy (as a software developer we know reproducibility is the key). Anyways it’s more of a matter of the development team becoming aware of the issue and having the time to investigate.

@Egika Good point, well presented I’ve just had a play with it & you’re right, there is now a ‘breadcrumb’ option in the map menu that didn’t used to be there so must have been added in the latest software (unless I just completely missed it previously). Either way it’s a fantastic tool to have & thanks for the feedback

@timecode thanks !

@Egika That is the one. Not sure the color change is a bug. A lot of other complications have lost color changes as well.

@Fermizante You are lucky because I am in the opposite situation. Sleep tracking was working good with the previous firmware and now with the last, no sleep tracking since 3 days and all actions done to correct the situation are not successful.

@leonidas I feel you as I’m currently have both Garmin and Suunto… But so is the way with software: it never is bug free. There are ways to avoid bugs or the reappearance of them, like test driven development. But unless you have a simple app, you cannot test all combinations of installations and settings or use cases someone might have. And TBF the accent color of a hand is not a major bug…

I’ve just taken delivery of a Race with a custom Canyon Orange strap, so hopefully the lack of negative responses into this thread are proof that I’ve done the right thing!

See here two triathlon 1500m swims. Same course, two different years. [image: 1743062095566-img_2483.png] [image: 1743062095598-img_2484.png]

@M2Oskie Same thing for me, my second hand has reverted to white as well.

@Strajamoned I slightly lowered the zones for cycling and forget it. Anyway, during my last ride, Zone Sense detected my aerobic threshold at the same value as when running.

@Elipsus “its more about being resilient if USA decides to reduce the capabilities of its “public” GPS, or completly turns it off.” That’s what I was talking about. Before 2000 this was the situation: https://www.gps.gov/systems/gps/modernization/sa/data/ Now, imagine that we went back to it, and I think it’ s not impossible so I think it’s a scenario worth thinking about and prepared to. What would happen to GNSS accuracy who use GPS and Galileo?

@Stefano-M64 Hi thanks - are you 100% sure about this? It does read that way in menus but its not how it works based on mine and other commenter experience. If so - which FW are you on? I will try to reset the watch and see if it helps EDIT: You were right, thanks again. watch restart fixed the issue.

@ChrisA It was all black. But I think it’s because of the loaded track, maybe it had some problem. With other tracks it worked fine. Thanks

@timecode SOLVED by updating the watch. Apologies for confusion. Will update the post header.

@dankcushions Thanks for the clarifications. However, I stand by what I said—OHR is garbage for sports across all brands and models, except for a lucky few whose physiology happens to align perfectly with their wearable for somewhat decent approximations. My point was simply in response to someone stating that HR is crucial. If it’s crucial, then you cannot rely on OHR for sports, regardless of the brand or model.
