Discovery Bank fails to achieve the Suisse Efficiency level on online banking in-App Authorisation

For the life of me, why Discovery Bank, set up an in-App Authorisation option for purchases if the damn thing does not give me the option to elect in-App approval or to get a direct text message (SMS) until the thing times out in a few seconds, and I have through the Woolies Dash purchase again, and again, and again, as if I have frigging century to do this. The Discovery Bank IT folks have failed the efficiency test on this one, you can forget about efficacy test for speed, Suisse efficiency, is all I ask for, at the very least. Good heavens.
