During a recent release aimed at performance improvement, we observed an unexpected disruption at 10:56 AM PT. Active users with expired authentication tokens were affected and redirected to a 401 error page, temporarily limiting their ability to use our app. This issue was an unintended side effect of the new release, which inadvertently overlooked the automatic refresh of expired tokens for these users. Our team has since addressed and rectified this problem by 11:23 AM PST.
