Bank apologises as glitch locks customers out of app

Around 2m people use the service, with the problem also hitting customers of Royal Bank of Scotland (RBS) and Ulster Bank, which are part of the same group.

RBS Group said it had now fixed the problems, which stopped customers logging in between 6.30am and lunchtime yesterday.

It is still trying to find out exactly what caused the issue but said the app was now working again.

The bank said that no other services were affected by yesterday’s problems, which follow a huge IT meltdown last summer and customers being blocked from accessing cash machines a few weeks ago.
