I have read the manual and some forums and want to clarify what is happening and determine if there is a problem. I received a new Zip roughly a week ago, and have been wearing it, but only today did I first add the new device to my account and sync via iPhone. The zip is only uploading today's data, so I wondered if it purged the data from the last week through yesterday because I had not added it to an account? If this is not the case, how do I get the previous days' data to sync and show in the app?
