Between the 5th and 9th November 2020, you have have received an email with the subject "World Walking - Fitbit sync failed", containing the message "World Walking has lost its connection to your fitbit account."
Please be advised that the issue underlying that email has now been resolved and your Fitbit should be syncing to World Walking again in the background. Additionally, we re-attempted syncing steps for the affected days so your totals should be up to date from 9th November onwards.
If you are still having problems syncing with Fitbit, please see https://worldwalking.org/help/article/5510/how-does-world-walking-sync-with-my-fitbit. If you see any error on your Settings > Apps page, please disconnect from Fitbit and reconnect to re-establish the API link.
