I usually enter my weight in the mornings via More -> Health Stats -> Weight in Connect Mobile, but this isn't showing the correct date for me with the new app, always the previous date. So when I enter my weight on the morning of 11/21, the list of entered weights on the Weight screen shows that weight having been entered on 11/20. However, when I view the Weight widget on the Connect web site, it shows the weight correctly entered (plotted on the chart) for 11/21.
This is with the latest Garmin Connect Mobile at this time, 3.1.1. I haven't been switching between time zones or anything fancy - just hanging out in CST. Thanks.
