does not sync and the HEART RATE SLEEP ASSISTANT does not WORK

With last update, Itdoea not sync with my fit-band, I cannot see day and night details!!!

Also the Heart Rate Sleep Assistant does not work automatically!!!

I should measure Heart Rate manually when I open the app. But in ex of 3. version, It was working time on time and It measured automatically. I activeted "Heart Rate Sleep Assistant" button, however it does not work automatically, I should measure manuelly. So I cannot use this function because of this updates. I wanna have ex version, It was working well!!!
