Test Send fails for Toast but works for Raw

when sending notifications to Toast, you want to make the payload adheres to the specific format and requirements is crucial. usually "payload incorrect" errors means there is a mismatch between the expected payload structure and what's being sent.

Here are a few troubleshooting steps:

1. Make sure the payload matches the Toast notification schema and all required fields, such as title, body, and visual elements, are present and correctly format. Also, the built-in test send feature in the Azure portal can help validate your payload before sending it to real devices.
2. You want to verify that your platform configuration for Toast notifications is correct, including the necessary credentials and certificates. If you're using template notifications, ensure that the template is valid and that you're providing the correct parameters.
3. Lastly, enable detailed logging in your Notification Hub to capture more information about the error. Look for any specific error messages or exceptions that might provide clues about the issue.

Hope that helps.
