Vitality app not working

I've been using the discovery vitality app for about 3 months now, the app always had bugs,but after the latest update, the app doesn't seem to work at all. First of all it keeps logging me out, and refuses to let me log back in. If I can log in, none of my apps that did sync to the app in the past, sync anymore. These include s-health and strava. Sometimes my virgin active workouts don't even sync<br> <br> I think it's really ridicules,have they not tested the app before doing an update??? <br> <br> Btw I have a galaxy s5, which should be able to run this app flawlessly, there are hundreds of people complaining on the app store, and nothing has been done <br> <br> Please fix this as soon as possible. Thank you <div><br></div><div><em>(Supplier name changed from Discovery Card to Discovery Vitality &amp; Vitality Mall by Hellopeter.com)</em></div>
