@Samuli-Sutinen I reported the problem, sent the logs, contacted Service, and nobody really knows much. It was an old bug, which was fixed, but it is happening again to some users. The solution from service is to reboot the watch, which I think isn’t very professional, not for a 1 week old watch, they should suggest replacing or sending it back, not to reboot the watch every day… You can check this chat: https://forum.suunto.com/topic/13274/sleep-tracking-not-working-after-most-recent-update/11?_=1764343827621 I hope they fix it soon, otherwise I will return it, because it seems that is out of stock (the titanium version) and it isn’t clear if they would keep the discounts I used.

@jannis said in Vertical 2 resources: It’s quite disappointing that so much time has passed, and Suunto still hasn’t solved this problem. This seems to be a theme lately… That said I found the Race S not too bad at resources. It’s not Garmin body battery, but can be quite good…

@2b2bff Thank you

I think with brushed titanium scratches don’t matter, on the bike for example you can just sandpaper them out!! But I am not sure how much of the V2 is titanium, is it just he bezel? Would it look odd if this was a different colour?

All’s well that ends well; synchronization is working again.

@kriskus, @Egika Thanks a lot for the feedback! I’ll take a look at why the text field couldn’t update. Regarding the difference between the 5k QR and the S+ QR that’s totally fine! QR codes can encode the same data and still look different due to factors like ECC level, matrix size, padding, and the chosen QR mode (numeric, byte, etc.). I believe the 5k version uses slightly different settings. For the watch, where resources are limited, I’m using a hardly reduced version of the algorithm that includes only the essential features.

@sky-runner Totally agree. I like Coros, but it has been even more obvious with some of the folks they pay to review their watches.

@2b2bff I’d be surprised to see a tilted rectangular display But I agree on the QC part.

@segi_pn why it should have a impact? it worked till the 28.11.2025 perfect like this. And i can’t update because it is not connecting. except if a message or call arrive on the Phone - the vertical inform me

@Jaxxdu I did just post in the iOS 3.6.0 thread there is something wrong with the sync too and I can see HR sensor failures almost every night. Like this: [image: 1765188757075-img_5051.png] I am no longer sure if I would go for Suunto device for diving. I always loved Suunto products, compasses, watches but seems like modern software and qa for that is just still in its childhood. This isn’t only a Suunto problem it’s true for other smartwatch, device and even car manufacturers. So I guess we shouldn’t rely on it unless it’s bare analog metal.

@Cyclepunk that’s the only strap that works hassle free with race 2 for me. avoid polar h10 - nothing but problems

@Brad_Olwin As I said in my original post this wasn’t the issue. This issue fixed itself and I am now able to see zonesense data on the watch and in the app, and I am not sure but believe one of the 2 following things fixed it: HRM 200 version updated to 5.40 Looking at the HRM 200 manual (Manual) I realized the device have 2 connection types: secure and open. Secure is when the device blinks green twice and open when it blinks green three times. I am not sure what was the connection type when I originally tried to make it work, but when trying again after opening this thread I made sure to use the open connection state. My hypothesis is that one of the two fixed my issue. Leaving this for future reference and future google searches, as when I searched this I didn’t find anything related.

My Suunto Race 2 stopped measuring blood oxygen after updating to version 2.48.16. Manual measurements don’t work at all, and the nighttime readings are inaccurate. A soft reset didn’t help.

@VoiGAS No because complications are not very readable. There is no accessibility options to increase text size.

@leehikes Have you installed the “Big numbers” SuuntoPlus app via the Suunto App watch configuration page?

@Mff73 only one phone

@pavel.samokha perfect. Thanks. All works again since last night.

I guess then that you should request Nolio to change their integration to Suunto, so that when they create a cycling SuuntoPlus Guide they set it also to be available not only for road but also for indoor cycling
