There is no problem in development mode. After receiving Build(.apk), there is no notification on android device. Below is the postman printout. There is no problem for iOS.

Hey @uveys89,

Based on the error MismatchSenderId, it is likely a result of your project using the server key or a google-services/json file from a different Google project. I’d recommend going back and ensuring that both the configuration values are tied to the appropriate project.

Here’s a Stackoverflow post with others that encountered the same error: firebase - FCM getting MismatchSenderId - Stack Overflow

Cheers,
Adam

Hello adamjnav. I solved the problem. I deleted the npm library. I also deleted the Google project. He improved when he did everything again.

Thank you!
