SurveyMonkey change history: Errors showing on Analyze charts

SurveyMonkey reported a major incident causing errors on Analyze charts from 2026-04-13 15:24 UTC to 2026-04-13 18:44 UTC, lasting 3 h 19 min. A workaround temporarily disabled an Analyze update so charts loaded without errors using the older version; a fix was later implemented and the incident resolved.
