Hi, We are trying to use the ongoing screening (OGS) feature from the "Refinitiv World-Check One API". We are able to create a case (POST on /cases) then to enable the OGS (PUT /cases/{caseSystemId}/ongoingScreening). When checked on the "Refinitiv World-Check One" browser UI the "Ongoing Screening" field in the "Case Manager" is effectively set to "Yes". The associated audit events mention that the OGS has been turned ON. When calling the endpoint for ongoing screening updates (POST /cases/ongoingScreeningUpdates, with a date in the past like in 2015 or older), the response is always an empty array even after a few days. So we do not get an initial match (what we expected). On the UI the field "Last Screening Date" remains empty. There is no audit event to let us think an ongoing screening happened since the case creation 5 days ago. When screening (manually using the UI) one of these cases the "Last Screening Date" is updated and an audit event is created. The call to the ongoing screening updates returns an empty array. There is no audit event to let us think an ongoing screening happened since the case creation. The "Last Screening Date" field on UI keeps the manual screening date value. Is there another action to perform in order to enable the OGS? Could this feature not be available to our account? Is the previously described behaviours expected and so, do we have a misunderstanding on how the OGS works? Should an audit event be added for each ongoing screening? Regards,
