Running Android 6.0.1; I've verified that I have the latest version of the app and the latest firmware. I'm on a Samsung Galaxy S3.
Using a Charge HR. I also have a Zip which I use occasionally when I can't have anything on my wrist, but I usually leave that at home.
I've got all-day sync turned on in the app but it does not seem to be working; I've verified that it will go at least three hours, possibly more, without syncing.
