Standard Bank App

I have been with Standard Bank for just on 40 years now with few problems. Lately I am having a major problem with internet banking App. For the past 3 weeks there has been numerous updates of the App. Since the first update I can not log into the App. It just shows an error message "Something went wrong. Please try again later" This has been going on for 3 weeks now and I have even had their IT department to help but they cannot. All that gets said to me is that it is the App. Why can't Standard Bank get their App sorted out. I am not the only person that this is happening to. Many people are complaining that this was not an upgrade but rather a downgrade. I am fed up now that I need to get to a PC to do internet banking and not phone banking. Standard Bank makes millions every year but they cannot get a simple App to work. Looks like they want their customers to join the other banking groups
