    WebGL builds on 2018.2.11f1 have the same issue and GetResponseHeaders returns null. Can it be an IL2CPP issue?

    When using with Unity 2018.1.8f1 and building an APK for Android with IL2CPP,
    There is still a similar problem in Galaxy Note 2 of Android 4.3.

    this bug breaks everything for me, when can we expect a release with a fix?

    I'm also experiencing this issue. This issue is blocking my team from upgrading our product to use Unity 2017, which would give us great benefits in other areas; however, because of this issue, I cannot recommend Unity 2017 to the team.

    Interestingly, GetResponseHeaders also seems to return null on PC standalone builds when there is no response body (like when the request method is HEAD). Worked fine in 5.5.3, broken after upgrade to 2017.2.0f3.

    This happens only when I builded on CloudBuild for Android.
    Not happens when I build on my PC.

    In our case, having "Content-Encoding": "gzip" and "Content-Type":"octet-stream" in request headers resulted in no headers being returned.
