Hey @lisiming, happy to share some insights and pass on a few next steps here.
In most cases a 404 Not Found implies that the resource you are requesting is not available, or that there is nothing on a resource to return. Have you already used to API to create a mobile platform application with this specific app? If not, will need to do so else there would be no resource to query, update, or delete.
Is the request you are making a POST to create a new mobile platform application ? If so, can you replicate the request you feel is generating an unexpected response, log the x-request-id header value returned and share it here? I would be happy to take a closer look! This header doesn't contain any sensitive info and allows us to locate request logs on our end.
I'll keep an eye out here - Cheer!
