New Online Approval Sucks!!!

Always happy with FNB until now, after you'll changed the way you approve online transactions I have endless problems with the notification being sent to the app for approval. To such an extent I have missed out on deals and promotions due to the app taking so long or not sending the approval at all the item goes out of stock on whatever I wanted to purchase. Maybe the one time pin was less secure but atleast it worked flawlessly.
