Hi Hiroshi,
Thank you for the reply. Allow me to assist you here.
Before answering your question/concern, could please provide us your sample ad ID's of skippable in-stream ads that have been returned and those API that have not been returned. In addition please provide us your complete request and response logs, with the request-id? If you haven't yet, logging can be enabled by navigating to the Client libraries > Your client library (ex. Java) > Logging documentation, which you can access from this link. We need this two information to help us identify and find out the reason for his issue.
Best regards,
