We're having trouble testing our Alexa skill using the Alexa developer console. Each time when the skill should respond with an mp3 audio the session crashes with an internal service exception. The issue appears since September 11, 2019, previously the skill worked just fine with the same audio files. Anyone else having the same problem? The response has a SSML type with the following format: "<speak><audio src="[audio_file_location].mp3" /></speak>"
