Goal: Average 10K steps per day each week - 300,000 for September
To keep things simple I'll round to the nearest 500

Date....... Steps ....... Remaining for goal
01...........7,000..........293,000

Kristine - my older Garmin devices would do what you described, but not very often. I started with a vivofit, then Vivofit HR, then a Vivoactive. That data drop thing happened on all of them at least once. 2 years ago I bought a full sized Garmin sports watch - a Forerunner 935. MSRP was pricey, but I waited for Black Friday and got it for nearly half off. I've had no issues at all with this last Garmin. I know someone who has the Garmin Venu. He loves it. I love the look better than my current more expensive watch. I chose what I did because of battery life. The Venu needs charged every few days. The 935 will last up to 3 weeks before needing a charge.
