Capital One Financial Corp is limiting how account data flows to outside apps for managing finances, prompting a backlash from the bank’s customers who say they have been locked out of their own information.
A technology upgrade led to the disruption, people familiar with the situation said. Plaid Technologies, whose software is used to connect banks with third parties, is unable to link with some Capital One accounts, according to the people, who requested anonymity because they weren’t authorised to speak publicly.
