On the dates on 12/15 and 12/16 I did not receive credit for Health IQ. I finished the quizzes on these dates, although I did not get credit. I did receive credit for 12/17 and 12/14.
I also added the Fitbit Coach, and did workouts on 12/3 and 12/5. I did not see the credit show up. If it did, I thought it was for the Weight Log as I did get credit for a Weekly Log.
