Some TSB customers reported problems accessing their online banking and mobile app after another IT update.
Around 50 customers tweeted the bank in the space of an hour this morning to say they were having trouble logging on, just 12 hours after TSB warned it would be updating its mobile app and customers should ensure they had the latest version.
TSB says it has now fixed the issues and has apologised.
This latest problem follows the huge IT meltdown which caused months of disruption, and saw customers locked out of their accounts and targeted by fraudsters.
