这几天一直解决不了这个问题，求助下社区大神，谢谢！
我的环境：
jdk 1.8
appium : 1.8.1

描述：进入 APP 后，从 native_app 跳转到 webview 页面 A,点击购买按钮后跳转到另外一个 webview 页面 B（这里我打印了一下，发现和前一个 webview 页面 A 的 url 相同，webview 名称相同，不过窗口 windowhandle 不相同，代码做了切换），然后点击元素的时候报错

我的代码：

    Thread.sleep(2000);
    //进入webview页面
    AndroidOperate.switchToWebview();
    tanxinCtyunHostPage.buyButton.click();//点击购买按钮
    Thread.sleep(2000);
    AndroidOperate.switchToWindowTitle("产品选购"); //跳转到第二个webview页面
    Thread.sleep(3000);
    productChoosePage.ziyuanzhongxin.click();//出问题的地方

//元素定位部分
/**资源中心*/
@FindBy(xpath = "//*[contains(text(),\"资源中心\")]")
public WebElement ziyuanzhongxin;
/**立即购买*/
@FindBy(xpath = "//*[contains(text(),\"立即购买\")]")
public WebElement buyButton;

程序运行的报错：

org.openqa.selenium.WebDriverException: An unknown server-side error occurred while processing the command. Original error: unknown error: Element <span class="mint-cell-text">...</span> is not clickable at point (35, 26). Other element would receive the click: <span class="mint-cell-mask"></span>
