I am so disappointed in this "upgrade", which appeared on my phone tonight as I started to work out. There was no problem at all with the former version, which I had used for almost three years; it was easy to use and user-friendly. With this new version, I can't even get started. Can't figure out why it needed to be changed. Furthermore, it would have been a small courtesy to warn users that you were going to change it instead of blind-siding us. Unfortunately, I won't be using my Myzone belt any longer as I'm not as tech-savvy as many of your other users likely are and am far too busy to try to wade through how to get started. Such a disappointment!
