Just wondering if this is a known bug ... (hi, I'm a subscriber, btw, have been for many years. hello)
So, there are (running) segments I complete on a very regular basis. For some of these segments, I get segment efforts recorded on my activity, but when I view the leaderboards for the segment, I'm not there at all - in fact the leaderboard says at the bottom (on mobile) "Tackle this segment to compete for the crown" as if I've never completed it at all.
Many segments I complete, even on the same activity are just fine, my effort is recorded, and I'm on the leaderboard (somewhere near the bottom usually).
Here's an example ... an activity from today, where I got a PR on a segment, but when I look at the leaderboard, I'm not there. There isn't even a "today" leaderboard.
Covering the basics - yes, the activity privacy setting is for Visible to "Everyone", and yes, I've tried using the "refresh segment efforts" link against the segment - it hasn't helped.
