Firebase手机号验证报错Error code:39，已做常规配置仍未解决

E/FirebaseAuth( 9898): [SmsRetrieverHelper] SMS verification code
request failed: unknown status code: 17499 Error code:39 I/flutter (
9898): An internal error has occurred. [ Error code:39 ]

已完成的配置操作 #

• 在Firebase控制台添加了SHA-1和SHA-256密钥
• 在Firebase控制台启用了手机号和Google登录方式
• 将google-services.json放入android/app目录，GoogleService-Info.plist放入ios/Runner目录
• 项目根目录已自动添加firebase.json文件
• 在Firebase控制台App Check中启用Play Integrity，并添加了调试和发布版SHA256密钥
• 启用了Firebase Blaze付费方案
• 在Google Cloud控制台启用了Google Play Integrity API
• 将应用上传至Play Store进行内部测试
• 等待1天以避免配额超限，确保配置生效
