HSBC Holdings (HKG:0005) and its unit Hang Seng Bank have been able to partially resume their app services after a glitch caused users to be locked out earlier in the day, the South China Morning Post (SCMP) reported Monday.

The apps reportedly failed to grant access to customers by showing the app service as unavailable, or asking for valid email addresses and phone numbers, despite the details being registered in their database.

HSBC is working to solve the technical issue and resume services, the newswire said citing a bank spokesperson. Some services are still unable, according to the SCMP.

HSBC's banking app had previously become inactive for a number of hours in January, the report said.
