Following our latest production release, customers may experience an issue where the audit trail change date filter displays an unexpected default value. This behavior has the potential to temporarily impact export functionality for those affected. Our dedicated engineering teams are actively investigating this matter to ensure a swift resolution and maintain the high performance you expect from our platform. We are fully committed to resolving this quickly and will continue to provide regular updates on this page until full functionality is restored.

Our engineering teams have developed a resolution for the audit trail filter behavior, which has already been successfully applied to all NA3 instances. The fix for our AP1 and EU3 instances is scheduled for deployment at approximately 1:00 PM PDT. Overall platform accessibility will remain completely uninterrupted for all users during this process. However, because the deployment specifically targets the audit trail page, this specific feature may be temporarily unavailable while the update is being completed.

Component(s) affected: Cash Application — Customer file loading Status: Investigating (update to Identified → Monitoring → Resolved as it progresses) Impact: Minor / Degraded performance — no loss of payment processing We are currently investigating a potential issue that may affect the loading of customer files. Customer impact is minimal. Cash Application continues to operate normally — payment files and records will still load and process as expected. During this period, some customer records may be populated with skeletal (partial) customer information. This is self-correcting: when the next customer file is received and re-processed, the complete customer data will be loaded automatically. No action is required on your part, and no payment or allocation data is lost. We will provide further updates as our investigation progresses.
