Non-working app, lost benefits!

The Discovery app has not been syncing or working properly since 21 Dec, which means that I have lost points and am now on a lower level than I should be. Hence, loss of benefits also!<br> <br> The biggest issue for me is that promises regarding functionality are made and not upheld, and no communication exists to indicate that Discovery is interested or are working on a solution.<br> <br> I know that the guys at Vitality have made it more difficult to make up the required points, the defective app makes me think that this is just another attempt to limit benefits to customers.<br> <br> What is going on??
