Nedbank’s new app causing problems for me.

Since Nedbank has decided to cancel the internet banking , and only use Nedbank ID app, my personal finances has become unavailable to me. My commercial business manager has tirelessly tried to assist .I have spent hours with the app department and various other departments on the phone. Absolute mess. I have already moved funds away from Nedbank due to this and are considering closing my account .I have opened FNB accounts for both my children since their app has always been much easier to use than Nedbank for me. This Nedbank ID would have been great for me if it was not for this huge hick up. The moment I link a signatory to my business profile, my personal profile also becomes available to psi I linked to the business..... How is this possible to overcome Nedbank? Surely someone must be able to change the app?
