TSB is continuing to limit access to its mobile banking app and online service after days of delays that saw customers unable to use their accounts.

Chief executive Paul Pester announced on Twitter on Wednesday morning that the services had been restored and thanked customers, many of whom had been left furious by the outage, for their "patience and bearing with us".

However a spokeswoman said the bank was limiting the number of customers to ensure those able to access the app received a normal service.

She recommended customers continue to try to open the app, but to close it down and restart if they encounter problems.

Those continuing to experience issues should contact TSB's telephone banking service, she said.
