About 1 in 3 times, when I end a hunt on my Alpha 300i, the resulting collection created in the Garmin Explore app will contain truncated activities. In a 40min long hunt, the activities for both the dog and the handheld might only be 4min long. Sometimes these activities will only be a few seconds long. The tracks still exist on the handheld and I can see them on the handheld's map, but I don't know how to make Connect download the missing information or recreate the "Hunt" collection.
