NatWest has apologised after customers were left unable to use its mobile banking app in the UK, leaving some unable to access their bank accounts.
More than 3,000 people have reported the problem on outage-checking site Downdetector since the issues first emerged at 0910 GMT.
The firm said on its service status website that its online banking service was still working normally, as were card payments.
“We’re sorry for any inconvenience caused and we’re working hard getting everything back up and running for you,” it said.
The BBC has approached NatWest for comment.
Customers have taken to social media to complain about the impact the IT failure is having on them.
One person said they had to “put back my shopping because of it”, while another said they were “waiting to go shopping” but couldn’t transfer money to do so.
NatWest has advised customers on social media that it has “no timeframe” for a fix, but said its team is “working hard” to resolve it.
Customers are being advised to access their accounts in other ways if they can – such as through online banking.
It is the latest in a long line of banking outages.
It emerged in May that 1.2m people were affected by them in the UK in 2024.
