We are constantly monitoring our campaign reporting to ensure 100% accuracy. Through that process, we discovered a technical error due to a Twitter product update to Android clients that affected some video ad campaigns from November 7 to December 12. The issue has been fixed but we wanted to share more details on what the impact was to our advertising partners.
Once we discovered the issue, we resolved it and communicated the impact to affected partners. Given this was a technical error, not a policy or definition issue, we are confident it has been resolved.
