近期相關修改內容的告知：
之前原生APP的眾籌失敗，所以目前沒有原生APP可供使用。目前使用的APP插件嚴重拖慢網頁加載速度，所以G20拋棄對APP的支援。APP無法使用我們不在解決，請通過網頁版訪問。
Notification of recent related changes:
The previous crowdfunding of the native app failed, so there is currently no native app available. The APP plug-in currently used seriously slows down the loading speed of web pages, so G20 abandons the support for APP. We are not solving the problem that the APP cannot be used, please visit through the web version.
