    I'm using these two scripts to handle downloading a file to PersistentDataPath. All works fine in Unity play mode and on the Rift.

    Code (CSharp):
    1.     public IEnumerator DownloadVideo()
    2.     {
    3.         downloadError = false;
    4.         downloadAborted = false;
    5.         uwr = new UnityWebRequest(videoURL, UnityWebRequest.kHttpVerbGET);
    6.         filePath = Application.persistentDataPath + "/Videos/" + videoTitle + ".mp4";
    7.         print("Downloading: " + filePath);
    8.         uwr.downloadHandler = new DownloadHandlerFile(filePath);
    9.         StartCoroutine(ShowDownloadProgress(uwr));
    10.         stopButton.SetActive(true);
    11.         yield return uwr.SendWebRequest();
    12.  
    13.         if (uwr.isNetworkError || uwr.isHttpError) {
    14.         Debug.LogError(uwr.error);
    15.         downloadError = true; }
    16.         else
    17.             Debug.Log("File successfully downloaded and saved to " + filePath);}
    and to display the download progress:

    Code (CSharp):
    1.     IEnumerator ShowDownloadProgress(UnityWebRequest uwr)
    2.     {
    3.         while (!uwr.isDone)
    4.         {  
    5.             progressBar.SetActive(true);
    6.             Debug.Log(string.Format("Downloaded {0:P1}", uwr.downloadProgress));
    7.             videoDownloadProgressText.text = string.Format("Downloading... {0:P1}", uwr.downloadProgress);
    8.             videoDownloadProgressSlider.value = uwr.downloadProgress;
    9.             yield return new WaitForSeconds(.1f);
    10.         }
    11.         if (uwr.isDone && downloadAborted && downloadError == false) {
    12.         print("Download progress = "+ uwr.downloadProgress+". Setting isDownloaded to true");
    13.             videoDownloadProgressText.text = "Download complete.";
    14.             Debug.Log("Done");
    15.         }
    16.         else { print("Download was aborted.");
    17.             videoDownloadProgressText.text = "Download cancelled.";
    18.         }
    19.     }
    However on the Oculus Go, it just prints a constant 0% downloaded, and downloads no bytes. I can confirm that the download folder exists and everything, and all works on PC.

    I also get no error messages in adb logcat.

    Not sure what the issue is...

    I should add, my android manifest has these permissions:

    Code (CSharp):
    1.   <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
    2.   <uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" />
    3.   <uses-permission android:name="android.permission.INTERNET" />
    4. <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
    5. <uses-permission android:name="android.permission.ACCESS_WIFI_STATE" />
    6. <uses-permission android:name="android.permission.CHANGE_WIFI_STATE" />
    7. <uses-permission android:name="android.permission.CHANGE_NETWORK_STATE" />
    8. <uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
