The chief financial officer of the financial technology company Revolut has resigned.
Britain's Telegraph says Peter O'Higgins, who joined the digital bank in 2016 after 12 years at JP Morgan, quit the company at the start of the year.
It comes as customers of the digital bank experienced technical issues accessing services earlier.
On the technical issues, the company said in a tweet on Friday morning: "We're currently facing some technical issues which are affecting our app's functionality - including top ups, exchanges and other features.
"Our engineers are on the case and we will update you as soon as possible.
"Card payments are currently processing normally."

Almost two hours later, the company said it was "back up and running".
✅ We're back up and running again! App functionality has been restored and all systems are running smoothly. Apologies for any inconvenience and thank you for your patience and continual support 🙌🏻

The UK-registered firm was started back in 2015 with a view that money should be borderless.
It offers global spending and transfers without exchange rates.
The company only received its banking licence in December last year.
More than four million people now use its services.
