android - Firebase FCM MismatchSenderID

Question

I have my client app with Android installed in several devices. I also have my Server app that send messages to those apps. The problem is that some devices receive the messages and other don't. I get the error "MismatchSenderId" when sending the message to those devices.

I divided the problem, so I open the firebase console and send notifications to my apps (I have the Token for each of them). So, using the console app, I get errors on the same devices that using my server. But as I said, every device is using the same app.

Any help of the reason?
