Your App, とよたのりのりチャンネル, currently has access to
Graph API v2.9 which will reach the end of its 2‑year lifetime

migrate all calls to Graph API v2.10 or higher.
Use the API Upgrade Tool to understand exactly how this change will impact your app.
Note: If you do not see any impacted calls in the API Upgrade Tool,
your app/code may not be affected by this upgrade.

我檢查了 API Upgrade Tool 的結果‑ 
我嘗試 Settings‑>Advance‑>Upgrade API Version 到 v4.0 但這並沒有更新我的應用程序。
我保留收到警告 ‑
