The September 2024 10K climbing challenge shows 0 of 10,000' while clicking on "View badge details" and showing the badge shows the actual number - both real-world and virtual climbs recorded on my Edge 840. Other challenges accurately track what I've done so far, despite having signed up for this month's challenges a couple days after my activity on the 1st.
It's been about 20 hours since the last activity was recorded (before I signed up for this challenge, as well as other challenges) and I've tried quitting the app and re-opening, as well as checking on Connect for the Web to see the same results.
I'll hit it no problem, but figured I'd report the issue regardless. I've not seen this before in challenges vs. badges and, as mentioned above, other challenges I signed up for after the fact this month are showing numbers for activities I started at the 1st of this month.
