React Native中配置第二个Firebase项目手机认证失败求助

我正在React Native应用中配置两个Firebase项目，已成功按照rnfirebase文档初始化第二个应用，但使用该应用进行手机认证时失败：

Android端报错 #

This app is not authorized to use Firebase Authentication. Please verify that the correct package name and SHA-1 are configured in the Firebase Console. [ A safety_net_token was passed, but no matching SHA-256 was registered in the Firebase console. Please make sure that this application’s packageName/SHA256 pair is registered in the Firebase Console. ]

iOS端报错 #

[Error: [auth/invalid-app-credential] Invalid token.]

我已在第二个Firebase项目的控制台配置了以下客户端凭据：

• iOS端：上传p8文件至Cloud Messaging标签、添加URL schemes
• Android端：配置SHA-1和SHA-256指纹

请问这种双Firebase项目的手机认证实现是否可行？我是否遗漏了关键配置步骤？另外我已在rnfirebase的Github仓库发起相关讨论。
