Mine was caused by hardware failure (built-in altimeter). Watch series 7. Gps-only. If i run with the watch only (leaving my phone behind) i would never get a reading for vo2max, in addition to ground contact time, vertical oscillation, elevation gained and flights climbed. If i bring my phone with me during the run, i get vo2max score after 25 mins of outdoor running. (As the watch is able to use altimeter data from iphone). The altimeter on apple watch sometimes works, for example after being submerged in water, after riding an elevator, or after flying in an airplane. It would work for several hours or days and then stopped working. I would open a compass app on the watch and get no elevation reading, that’s how i knew it was broken and the reason I couldn’t get my vo2max score if i workout with the watch only.
I’m pretty sure it was those iOS 18 battery saving tips videos that dropped every new iOS version had everyone turning off most location settings because it was “wasting” battery. Some of the settings makes sense but we should not blindly toggle settings without knowing what services uses it like emergency sos. I see this every so often happening to location related services like HomeKit automations whenever someone turns off the settings based on the video recommendations😅
Did you have this issue? Where you able to pinpoint when it started?

I’m about 95% sure I did that. :-)
Thanks, I had the issue. Made the changes and boom, its back
Awesome!
I actually had to look up what VO2 max was since you didn’t explain. Also, it only applies to those using an Apple Watch.
Good points.
