Received alert doesn't show audio in the alert timeline

If you view an alert before the first 15 seconds ends, audio is still being delivered. At the beginning of an alert, we send four 15-second audio files, then two 30-second audio files.

The sender of the alert may have denied microphone permission to the Wearsafe app. To provide audio and use the full Wearsafe Safety System, each Account Owner or Device User must grant permission to the Wearsafe app to use the microphone in their phone’s Settings app.
