Discrepancy in Cast Credits Not Updating After Approved Submission

Hello IMDb Community, I recently submitted a change to the cast credits of a film, and the status says “Approved.” However, the cast list on the film’s page has not been updated—still showing the old cast. I’ve waited some time, cleared cache, refreshed the page, and even checked with different accounts, but the change doesn’t reflect. Has anyone else experienced this delay? Is there a known backend lag in syncing approved contributions? Also, while reviewing my submission history, I noticed occasional comments about “not meeting guidelines,” but this change was straightforward and well-sourced. It reminded me of when I browse a [Dunkin Donuts Menu](https://thedunkindonutsmenu.com/)—ideas or requests get listed quickly, but sometimes actual updates take longer to serve. My questions: After a contribution shows “Approved,” how long does it usually take for the system to update the public page? Are there cases where edits are approved but not implemented (for example, due to conflicts or internal moderation)? Whom can I contact if an edit remains unreflected for days? Thanks in advance for any clarity or shared experience!
