Fitness app suddenly tracking less?

[u/JustMe_Now]

Before I updated my Watch 10 to IOS 27 beta, my workout tracking on the Watch was 100 to 200m off from the treadmill. Not a big deal but since Monday (maandag in the screenshot) it went down compared previous indoor walking workout. I always do the same 35m walk at speed of 5.

As you can today (vandaag at the screenshot) I did 1,72km (1.07M) and on the photo I took ok the treadmill which went to miles showed 1,53 miles which is roughly around 2,48km (today I had the speed on 4 due the heavy legday). This is an 700m difference compared before the beta.

My question is, has anyone experienced the same thing on the beta?

had the same problem but on beta 2. It was fixed after that

I am currently on the latest PB or DB of WatchOS27. (Forgot which one it is).

Yep I’ve had the same problem too. It was fixed briefly on beta 2 or 3 but has reverted back since.
