最新版Unity SDK在最新版Unity中不能正常使用

SDK 版本：LeanCloud-Unity-SDK-20180703.3.zip
Unity版本：Unity2018.2.0f2
问题1：运行时报错
MissingMethodException: bool UnityEngine.Application.get_isWebPlayer()

问题2：使用以下代码注册时报错：
public void OnSignInClicked(){
var user = userName.text.Trim();
var pwd = password.text.Trim();
AVUser.LogInAsync(user, pwd).ContinueWith(t =>
{
if (t.IsFaulted || t.IsCanceled)
{
var error = t.Exception.Message; //
}
else
{
didSignedIn = true;
}
});
}
