If you will look at my Go365 calendar showing all my workouts far exceeding the required 8 per month, but not one activity credit has been issued for the past two months. This is also the case with my running partner. We do several miles a day but no credit. Also I go to the gym at least 3 times a week and yet there's no activity credit even well after the month has ended.
We use Runkeeper registered with Go365. Runkeeper has worked well the past few years and according to our Go365 calendar, you are receiving the information.
