If you missed a day of tracking during the challenge, you have the opportunity to update your challenge-tracking activity while the challenge and plan year is still active
In some cases, a challenge will have a seven-day grace period (beginning immediately after the challenge end date) in which you can add or update your challenge tracking activity within the challenge start and end dates.
There is no seven-day grace period on the Health Assessments, Biometrics or University course challenges.
