UPDATE 10/12: This issue has been resolved.
We are currently investigating an issue that is preventing activities from being shared from the Strava website to Facebook. Athletes are describing that after hitting "share" from their Strava activity page, they are no longer receiving a "successfully shared to Facebook" message and the activity does not get shared to Facebook.
In the meantime, you may still be able to share successfully from the mobile app.
Thanks for your patience as we work to resolve the issue!
