Dreadful app experience

The Nedbank app is becoming painful to use with the selfie feature. The app will not allow me to add a new beneficiary without selfie verification (even though I have set finger print and pin code as my preference). The selfie functionality does not work and says I need to go into a branch to load a beneficiary. I'm trying to make an urgent payment but now I can't load the beneficiary until I'm able to get time off work to go to a branch (my husband has had to make the payment for me). I have tried retaking the photo in various different lighting conditions and it says it can't recognise my face. This is the opposite of convenience. Please let customers use finger prints instead - it is much, much simpler and more reliable.
