Deep Links don’t work (Club Activities)?

Hello,
since a few days, the deep links to club members’ activities won’t work (activity and person url invalid?)…

The latest activity-updates are retrieved successfully, though, so the blog-integration seems to work in general (settings haven’t been touched since initial setting up, no errors shown).

All person names link to: https://strava.com/athletes/
All activities are individually and correctly named, but link to: https://strava.com/activities/

Thanks in advance for checking and your help,
Thomas
