我在 UCWA 的 Skype Online 版本中遇到了一些奇怪的行为。我与使用普通 Skype for Business 客户端的用户展开对话，并继续与他们来回聊天。有时，在对话过程中，我会从 UCWA 事件资源中看到看似错误的参与者添加和删除事件。
例如，我将在一个 GET 事件资源上收到参与者添加的事件。接下来，我收到一个参与者删除的事件。第三，我收到“已删除”参与者向我发送了几条消息的消息事件，有时还有更多参与者添加/删除事件。
这是我的一个日志中的一个示例：

当用户实际加入对话或关闭他们的 Skype 对话窗口时，我不确定我应该如何区分这些添加/删除的事件和真实事件。我已经尝试关闭参与者消息事件，但后来我发现当 Skype 用户关闭他们的对话窗口时，我不能可靠地收到参与者消息删除事件。我对使用 UCWA 还很陌生，所以我不确定这是否是 UCWA 的本地版本的正常行为，还是 Skype Online 实施的错误。
我知道 Microsoft 刚刚在 Skype for Business Online 中启用了此 UCWA 功能，但与我之前使用 UCMA 或 Lync Client SDK 的行为相比，它似乎非常不稳定。
