On my I phone x for the last 2 days every time I try to sign in with my correct password onto the standard bank app the app disappears and takes me back to the home screen. Tried deleting the app completely and reinstalling it , but the same problem occurs . Updated my software & have tried everything, have been on hold for ages & have been told the problem has been escalated to the IT department but am really having no joy . Wondering if anyone else has experienced this or has a Soloution . Would be very grateful. .
