NatWest has apologised after customers found themselves locked out of the bank's mobile app earlier today. Around two million 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.
The bank is still trying to work out what caused the problems.
All our mobile banking applications are now running normally. We apologise again for the inconvenience caused to our customers.
