Longform TTS not being played on a phone, however it plays in the web simulator

[ghost]

Hello everyone,

I'm having a bit of an issue getting TTS to work in a Google Assistant Action on Android. I'm trying to make a "flash briefing" action that reads some news headlines and summaries, and these play on the web simulator. However on Android, it will just say "Here is the Radio NZ briefing" and close the conversation.

Does anyone know what I can do to get it working? Is this possibly a bug?

Just saw this here: https://developers.google.com/actions/assistant/responses#media_responses

Media responses let your Actions play audio content with a playback duration longer than the 120-second limit of SSML.

I tested it on Android with a smaller SSML response and it's now working - I feel that this constraint should also be reflected in the behaviour of the web simulator.
