Mercantile Bank application issue worts application

The Merchantile application is horrible to use the application doesn't want to open. It just goes to a white screen or loads and don't open.

The application also is difficult to manage not easy at all to work tru you banking details and is a real waste of time. Why can the application be like the Capitec Bank application wich is the same bank basically. Hope this application can be sorted out. Even if you work on the Capitec app second page log in of Merchantile bank is much better. But the you have to wait for a OTP numbers every time even though you put you pin. The Merchantile application on its own is horrible to use and not user friendly interface. Half the time it doesn't work other times you struggle to log in
