Hi all,
I’m trying to use Entra ID (Azure AD) SSO with the LINE WORKS app, but I get the following error:

Failure reason: Browser not supported  
Additional details: The user is using a browser that does not support device identification so the device state is unknown.

According to Microsoft docs, this happens because the LINE WORKS app uses an internal browser (WebView), which cannot perform device compliance checks.

Does anyone know how to solve this? For example, forcing the app to use an external browser (Safari/Chrome) or adjusting Conditional Access policies.

皆さんにご相談です。
現在、LINE WORKS アプリで Entra ID (Azure AD) SSO を利用しようとすると、以下のエラーが発生しています。

Failure reason: Browser not supported  
Additional details: The user is using a browser that does not support device identification so the device state is unknown.

Microsoft のドキュメントを見ると、LINE WORKS アプリが内部ブラウザ (WebView) を使用しているため、デバイス準拠 (compliant device) の判定ができずブロックされているようです。

どなたか、この問題を回避する設定方法（外部ブラウザを使用する設定や Conditional Access の調整など）をご存じでしょうか？
