I have been having issues with VO2Max and Performance condition updating / showing values for runs since firmware update 8.20. Everything else seems to work but I get no values for VO2Mac and Performance Condition on my runs. Nothing changed - I am doing the same runs I have done the last few months, HR, speed, etc are all showing and updating. I also get the usual body battery, stress readings etc. Anyone have clues as to how to fix this? Given this occurred with firmware update 8.20 I suspect this is a software problem and may need an update.
