Ulster Bank users were facing more technical difficulties today after a new glitch in its system meant payments into the bank were not processed overnight.
The bank said this morning that it had resolved the problem and any customers who are out of pocket as a result will be compensated.
"Some files were delayed through our payment system overnight and these payments have now been made," the bank said in a statement.
"We apologise for this delay and if any customers have been left out of pocket, we will put this right."
This is the second time this month that there have been problems with the bank, while last year many customers were locked out of their accounts for over a month.
At the beginning of December, Ulster Bank was forced to apologise after thousands of its customers were left without access to their accounts following a breakdown in system here as well as the UK.
