I opened the new app for the first time yesterday. I really dislike it. I had the app set up so it displayed exactly what I needed to track, combing info from the Vivofit and the 610 on the same page. Now I've got a very ugly front page, and have to use menus and scrolling to find the pages. It's awful.
Biggest problem is that my step counts are now showing on the wrong day. Yesterday's effort (Apr 22) is showing under today's date (Apr 23) when I go to Steps via the Dashboard. The data is correct on the website.
I find that when I look at the dashboard first thing in the morning, I see yesterday's data. Then if I go to settings or devices and the return tot he dashboard, I see today's data. I'm not sure why it doesn't automatically update the dashboard display immediately.
