Save image from system share dialogue doesn't work

[nicloay]

Environment

iOS version: 13.3 (on iPad 7th gen) unity 2017.4.31 plugin version 1.2.1

Info

With standard code

    private void DoShareImage()
    {
        using (var payload = new SharePayload(null, OnShareDone))
        {
            payload.AddImage(GetSelectedTexture());
        }
        Debug.Log(">>> 1");
    }

    private void OnShareDone()
    {
        Debug.Log(">>> 2");
    }

Most of the system action works (share in facebook, send by email, etc...) But save to device do not unfreeze unity (Popup disapear, but unity probably don't receive signal about that, so Debug.Log(2) is never called). The image by the way is stored to the gallery anyway.

here is a log from device

If comment UnityPause(false|true) in the NSSharePayload.m - the app is obviously not freeze/unfreeze and save works as expected (not a solution, but just to prove that dispatch_async is not called).

Similar symtoms as here

The fix here is to not pause Unity Engine.
