recently upgraded my vivosmart to a vivosmart HR+. The first week all was well but now it will register me sleeping while I'm at yoga in the evening all the way through the night. The wake time is always correct. When viewing on connect it will show movement during the evening and night hours but still count it with sleep. When editing it to the correct sleep time I'm not sure if it is even an accurate look at the sleep patterns......anyone have a way to solve this
