I used this app for about 3 weeks and it did everything I needed it to. It easily tallied my net carbs & broke down fat/protein as well. As I built up a cache of favorites, it got quicker & easier to use. Today I went to use it at dinner time and noticed my data for the day was gone. Then I saw that all the prior days were gone, as well as my cache of favorites. I got a notice saying my session had timed out and that I should log back in. (A first in 3 weeks). It took several unsuccessful attempts to log back in. Once I did, everything was still missing. Its like I never used the app. This is very discouraging as until today I thought the app was great. Please get this fixed, asap.
