I have been reporting my vision exams, as well as my childs, and never receive points. I was also told I would get certain amount of points for my daily steps and I have yet to receive any in the last couple months that I've had my fitbit.
Are you able to view your steps for each day on your Fitbit account?
Also, please keep in mind that you are only able to submit completed activities for yourself via the mobile app. If you are submitting for your children, you will need to submit the proof via the Activities page, or the Communication Center, on your Go365 account.
