After setting up Ad Placements (following the ironSource/Playfab tutorial) in the Ads section and upon calling GetAdPlacements in the Client API, we're getting an empty array from the server :
{ "code": 200, "status": "OK", "data": { "AdPlacements": [] } }
It may be worth noting that those Placements do not have any rewards attached to them, but the GetAdPlacement API documentation seems to say that they are not mandatory to work.
Is there anything we're missing in order to get data with this API call ?
