VERIFYING NEW DEVICE ON BANKING APP

I am writing this because I'm very frustrated by FNB's lack of communication regarding re-verifying your phone's banking app.

I got a new phone a week ago, downloaded the FNB banking app and it was business as usual. Today my banking app / online banking service decided to NOT send me approval notifications via my banking app.

In other words, if I want to take any online action, like making a payment, I cannot approve the action via my banking app as it doesn't send the approval notification request to my banking app anymore. It appears to be sent to my old phone - which I have "delinked" by the way. I'm completely stuck now because I cannot approve anything.

Now I have to take 30 - 90 minutes to call around and figure out what's up with my banking app / online banking service. This then usually ends with me having to go to the branch - which I prefer not to do.

What gets me down is the fact that I have to figure out what is going on. Why can't FNB notify me that I suddenly need to re-verify my banking app AND that's why the approval notifications aren't coming through anymore? Followed by instruction on how to resolve it then and there.

The way to rectify an issue like this is much too messy. You can help me by sorting this out, please.
