Post launch tweaks to Affinity Analytics and data download

After our recent Beta launch of our Affinity Analytics there were a few lingering things in the UI and data downloads that needed fixing. So last night we deployed an update to clean it up - the changes weren't large so you may not have noticed. The biggest change was in improved CSV download of your audience affinity analytics and historical trends. There's a lot of good data in the analytics we compute but if there are things that you'd expect to see or would like us to add, just give us a shout and we'll see what we can do to get it into the reports.
