How do I fix the "SenderIDMismatch" error when sending push notifications to Android devices using the Pushwoosh Expo plugin?

The "SenderIDMismatch" error indicates that the Firebase Cloud Messaging (FCM) Sender ID configured in your application code or Pushwoosh Control Panel does not match the Sender ID associated with your Firebase project.

To resolve this:

1. Verify your FCM Sender ID: Go to your Firebase Console, select your project, navigate to Project Settings > Cloud Messaging. Your Sender ID is listed there (it's the same as the "Project number").
2. Check Pushwoosh Control Panel: Log in to your Pushwoosh account, go to your application, and navigate to the Android platform configuration settings. Ensure the Sender ID entered here exactly matches the one from your Firebase project.
3. Check Application Code: In your Expo application's initialization code for Pushwoosh, ensure the project_number parameter matches your Firebase Sender ID. For example:

   import Pushwoosh from 'pushwoosh-expo-plugin';
   
   Pushwoosh.init({
     pw_appid: "YOUR_PUSHWOOSH_APP_ID",
     project_number: "YOUR_FCM_SENDER_ID" // Ensure this matches Firebase Project Number
   });
   

4. Verify google-services.json (if applicable): Although initialization often uses the project_number directly in Expo, ensure the google-services.json file used during the build process (npx expo prebuild) corresponds to the correct Firebase project and contains the matching Sender ID (project_number).

Correcting any discrepancies in these locations should resolve the "SenderIDMismatch" error.
