ABSA new online app

I have been using the ABSA banking app forever. ABSA decided to change it. I downloaded the new app- tried numerous times to register/link my iPhone to the new upgraded up. End of month and not being able to do banking whilst away from home has now become a nightmare I tried the facial download option repeatedly with no success- which doesn’t make sense seeing that an accident with facial scars will deny access to the app???? But to name one scenario!!!!! Utterly frustrated and very very time wasting and consuming
