Investigating
As of 13:20 UTC, we started seeing scoring delays with our Enhanced Math Scoring service in the US-East-1 region. No data loss has been observed and all sessions have ultimately been scored. As a knock-on effect, the Data API Scoring endpoint is experiencing intermittent availability issues. No authoring or assessment delivery has been affected.
Learnosity Support and Systems Engineering teams are actively investigating the issue, and will follow on with an update and resolution as soon as possible.
