I've had my previous scales replaced for broken WiFi module and I haven't had the smoothest ride with the replacement unit either. After taking the measurement, the data doesn't sync, **however** it does successfully sync once a day, at around 2AM. I've checked router logs and there's clearly more data exchanged at that daily occurence than any other time when scales connect. As you can see in the screenshot, the router-scales connection is the same (wifi channel, device, etc.).
I suspect some bug in the logic of post-measurement-push, versus daily checkin with Connect servers.
