Customers of Ulster Bank found themselves unable access their mobile banking application today.
A spokesperson for Ulster Bank have confirmed to Independent.ie that the bank is “experiencing some issues with the app.”
“Not everyone is experiencing these issues - they are intermittent problems. But we are working hard to get this resolved,” she said.
Earlier today, parent bank Royal Bank of Scotland (RBS) apologised to customers on Twitter for similar glitches – blaming high surges of traffic.
The errors occurred as people were trying to check their balances in the run-up to the weekend.
RBS said it had seen "record" numbers of people trying to access mobile banking and saying that "high traffic" was preventing some customers from being able to log in.
It said: "We are currently experiencing record usage of our mobile banking app. Over 5,500 customers are logging on every minute."
