   We began investigating reports of videos not loading from the catalog on the web.
2. 17:30 UTC - Identified:
   We identified the root cause as a recent deployment, which included a feature condition that erroneously caused redirects when users clicked on videos, redirecting them back to the catalog.

Root Cause and Resolution

The problem was traced to a deployment today that included a feature condition for redirects. This condition mistakenly caused redirects back to the catalog when end-users clicked on videos. Our team quickly identified and implemented a patch to fix the redirect issue.

Preventive Measures

To prevent similar issues in the future, we will ensure all redirect features are applied with proper feature flagging. This will help avoid erroneous redirects and ensure smoother deployment processes.

We apologize for any inconvenience this issue may have caused. Your patience and understanding are greatly appreciated.
