Alexa.DeleteReport Banner tip "server is unresponsive"
I am certifying with WWA,In the WWA authentication process Procedure:
1. Delete device from 3 Party app by swiping left on the device and selecting Delete.
2. Perform a device discovery in Alexa Smart Home
Expected Result: The banner "Device is unresponsive" is displayed on the device control page within the Alexa mobile app.
I've implemented DeleteReport, and Alexa banner tip"Server is unresponsive" after the device is deleted. How can I meet the requirements of WWA?
