Mine is fine.
It looks ok on my side. It looks like you didn't do the full challenge. Did you bike 75 km? Do you have the badge?
but it is gray and in past challenges ? it should be in top page
It ended two days ago. So it should be in the past challenges.
it's a challenge for november, we are the 9 !!! So the challenge isn't over I think
As the description states 1 Nov to 7 Nov. Not all challenges are month long, furthermore there will be challenges only for this weekend coming soon.
Check the dates for it. 1 November to 7 November. The name just says that is is a challenge in November. Not for the full month.
sorry, but with my display bug, I haven't seen the date 1-7 november :( But never mind, I will next month
