Garmin has received reports of Vo2 Max from the Forerunner 235 no longer updating on Garmin Connect. The engineering teams are actively investigating the cause. We do apologize for any inconvenience that this has caused.
I run almost every day, and I'm using an HRM strap + foot pod each time.

Just to clarify:
- Are you running outdoors and using the factory-preloaded Run activity to track it?
- Do you run for ten or more minutes continuously maintaining your HR in an anaerobic HR zone?
