Hi kmunson, thanks for the quick response! I tried that option on my Android phone/app as well as my PC (in regular and compatibility mode) without any luck. However, I found a link: View Weight History>Enter Historical Weight Entries (on the lower right hand side) and it worked as you described. I am not sure why the calendar isn't always set up to accept weights from previous dates...but oh well. I appreciate the quick response.
I wish you well in your diet!
