The app release process fails after approval when clicking 'Release Now' in the app submissions page. The failure is caused by the GraphQL mutation OCDevManageApplicationSubmissionScheduleReleaseDateModalMutation returning error code 1675030, indicating a server-side failure during the release scheduling operation. The error originates from RelayGraphQLRequestUtils.createErrorFromPayload, suggesting that the issue lies on the server-side rather than the client-side.
