Fixed - it should all display correctly now. You can use this thread for issues or ideas. Happy riding!

@Dimitrios-Kanellopoulos iOS… do not know with Android. It happens from time to time, at the moment it is gone…

@baaaa trails were brought back to 500m zoom level with 2026 Q1 FW release Though unfortunately it was not made available for Vertical 1

@Nelson-Diogo Only thing I’ve noticed was my Run removed a watch face by itself spontaneously today. Had to go into the Suunto mobile app and set it as active from there as it wouldn’t show up on my watch but it said it was still installed in the app.

@emkei Don’t sweat it, the platform is most likely dead.

@bitcoin did you solve your problem? I had the same error on my Suunto 9 Peak Pro few days ago, now i can’t use it without constant connection to it’s charger

@Nelson-Diogo I have Suunto run since the beginning of October. From the first day, the pulse measurement on the wrist was not good. It was very bad. That’s why I bought it soon chest strap. But the last two updates have significantly fixed that problem. However, when I do strength training with a kettlebell, the heart rate measurement on the watch is not good.

I usually always check if the altitude shown by the watch is correct, if not it can be set manually or auto adjusted. Apart of that, the data look very scattered, I agree with Egika about strong wind or dirty sensor. Did you get the same behavior also other times? in this case the pressure sensor could be defective.

I have this problem with the Suunto HR belt since November 2025… I reported this several times here, and I contacted the support… they told me to send logs… it’s a problem with SV1… it’s a problem with SV2… with two different HR belts… and that’s why I don’t think that this is a problem of a belt or a watch… this is a Suunto problem, but it seems that they don’t care about this…

I did reinstall the previous version 6.8.13 and that fixes the issue. So the new version from june, 6.10.7 has a bug, at least with suunto 9 Baro. There is no more watch firmware update for a 2 years (version 2.26.8) It could be an incompatibilty between this apps version and that firmware version.

@sky-runner you might be on something here. I too was starting activity with wrong S+ (due to the fact it resets everytime you do a guide) and had a crash. now that I leave only one s+ (2 including the guide) I haven’t had restart. There were a couple of times though that my watch crashed without going to the menu but I always had on route navigation!

@Matúš My hypothesis is that there are some extra features that do not really work well together. Test 1: new battery installed because watch could not last for more than two days which is somewhat below specs. Before battery switch the sleep tracking was unstable, after the change it never came back. Test 2: turned of heart-rate measurement completely since it is no use … Surprise it is still trying to ignite the measurement LEDs ??? Restarted it several times, being more than a week since I received it back. Multiple trainings done, they worked out OK and battery time seems to have improved since I can use the watch more than two days on a charge now. However it is entirely unlike the other Spartan Sport WHR I own which can be worn a week and still has 80% of battery power. Both have new battery but remarkably different performance, sleep recording broke something in the 9PP as far as I can deduce.

@2b2bff Sure…if you’re doing an interval workout I agree completely. But during a run without any “targets” it still happens. Haven’t found a reason (or how to make it stop) yet.

@Gilles-D. said: how to revert to previous FW with watch V1? Settings > General > About scroll all the way down to the end hold Down button to enter Debug menu Select OTA pkg

Any updates on improved accuracy atm?

Please Suunto give some love to this app …

@Arnaud-STRAUCH Hello Arnaud Like you, I am very much looking forward to the CCR mode! If inserting a POI while diving would be a plus, I think the problem would come from the reliability of its geographical position since underwater navigation information is essentially inertial and comes from the compass! In my club, we face the same problem and apart from noting bearings and distances or using a SMB to mark the location, I don’t really see any cheap solution. Laurent (Pau Océan)

@soryp I confirm I did it twice following your instructions… That’s why it is so strange !
