Shambolic rewards system

I have been a member of Virgin Active Health Clubs since 2016 and am deeply disappointed with the new "rewards" they promise to members. The app one has to use to "sign out" after a 30 minute or more workout does not work: it either shows "password incorrect" or "internet connection failed". In addition, some members who spend 30 minutes plus for more than 2 times per week, get allocated 6 tall smoothies as reward and others only receive 1 small smoothie for the same amount of workouts, at the same club (Vereeniging). Even scanning one's physical card does not help when the app is not working. This is really disappointing and shows disregard to the loyal members who do not exploit club visits for Vitality points only, but who actually do work out and make optimal use of the facilities and support the business partner - Kauai - even when there aren't promotions.
