Working great, but can't access historic data

Setting up was very easy and and I was quickly up and running. The product seems well built, the screen is clear, and the Smart Life app connects fine. But I was hoping/expecting to be able to look at records from the past - there is very limited provision for this in the App (no way to view data out sensors side by side for example), and no way to get the data out to use it elsewhere. (There appears to be a download button, but it doesn't work.)
