Hi,

Since 2nd Dec the VO2 max has not updated on my Fenix 5s plus.  I don't mean my personal VO2 max hasn't changed, I mean the reading is showing my VO2 max was last updated on this date.

I walk about 6km every day (with GPS on) and run occasionally too; the last update was on a day I ran, but usually it would update after every walk or run. 

I haven't changed anything or tinkered with the settings - any suggestions please? 

Thanks in advance x
