I'm sick and tired of it not connecting, having to log back in, login being invalid, and trying to do it all over again. Since I have gotten this new machine due to the recall, it has been a problem at least weekly to see information and not being able to login in. It says login is invalid. Why is this so difficult? Why make this impossible to view the data to know how I'm doing? If you can't get the app to work, then give me what the doctor uses.
