On August 21st, between 7:30 UTC and 10:56 UTC, new calculations could not be saved. The features for editing and running calculations remained unaffected.
No customer data was lost.
The incident was resolved by reverting the changes that had affected the calculation creation.
The issue was caused by a code change that targeted a bugfix for an unreleased feature. The change also removed the code responsible for backward compatibility.
We will enhance our change management practices by introducing additional reviews and validations before removing backward compatibility elements, ensuring that such changes do not disrupt existing user workflows.
