Discovery Bank APP failure

So glad I didn't move my accounts from Nedbank to Discovery bank. I spent over 30 minutes on numerous calls over 2 days, just to get my secondary card holder on the APP, but it does not work. I followed all the steps from the consultants and still no joy. Just lucky I didn't move all my accounts over, I would have been in a serious mess right about now, when I need to use the functionality of the APP. STAY AWAY .
