We have identified an issue affecting secure emails sent via Paubox (a secure email service provider). Paubox recently introduced an unexpected change in the formatting of timestamp data returned by their service. As a result, certain date fields are not being processed correctly within Welkin and may appear invalid. Our team is actively working on a solution to handle the updated format while we also coordinate with Paubox to ensure alignment with their published documentation. Impact: Users may see incorrect or missing date information for emails sent via Paubox. No other Welkin services are impacted. We will provide updates as soon as a fix is deployed.
