@Squirrel Thanks a lot! Now it makes sense. I am new to TrainingPeaks and I tried to study how the CLT, ATL and TSB are calculated and I though that I understand it but then different text description of values in the app and watch totally confused me. Also in the watch manual there is no deep description of widgets, there are just few general sentenses without needed details. I think that this would be an easy fix which helps people to start with training peaks. Also lots of people complains than Suunto watches are often inconsistent with the app and this would help at least a bit with this issue…

@Mff73 thanks, do you know where I can track progress on the issue. Strange that support didn’t mentioned it and let me perform a factory reset. Suunto is requesting to send back my watch for analysis. Sounds a bit drastic, as it will probably take 3 weeks before it will be back or replaced. I have rolled-back the software update on the watch and disabled software updates in the app. So far so good. Assuming FW=firmware What does AFAIK mean? Update: since the rollback, the watch and app are working perfectly again. Update 2: Watch and app are still working fine. Did 3 work outs, 2 with gps of which 1 with navigation. I noticed that the battery consumption is a bit lower then before (battery consumption stayed the same after the upgrade) Could be due to the factory reset earlier.
