Summary AI Generated

Fivetran's Twitter Ads connectors experienced sync failures for 3.9 hours due to a third-party authentication error (code 215) from Twitter's API when fetching async job results. The issue was caused by Twitter's API returning "Bad Authentication data" errors on their side. Fivetran resolved the problem by implementing a workaround that skips the problematic endpoints for affected accounts, restoring normal connector functionality.

The issue has been identified and we are working to resolve it.
