Hello, I'm having an issue when sending a POST request using UnityWebRequest on iOS in 2019.1 I'm using an UploadHandlerRaw and if the data is bigger than 2K, then the data gets truncated and never sent to the server resulting in a timeout error. The same code on Android and PC Editor works fine. I noticed in the release notes: iOS: UnityWebRequest will use new backend based on NSURLSession. Old NSURLConnection backend is still available (commented out in trampoline). which seems kind of suspiciously related to my issue.
