Artifacts expired but can be downloaded

Hello Team,

We have a .gitlab-ci.yml which has been set with the artifacts created to expire in 1 hr artifacts:expire_in: 1 hour.

Yet they can still be downloaded way after 1 hour.

From the Sidekiq Jobs Dashboard I can see the cron job for expired artifacts deletion runs every 7 minutes although it seems to do nothing with them.

Is there any additional setting which enables the cron job to work?
