Clear Notice When a Session Has to End (v3.15.1)

If Hedy can no longer capture audio during a session, it now ends the session and tells you why, instead of carrying on without sound.

On Mac, a card stays on screen until you see it, so you notice even when you are in another app.
On Windows, iPhone and Android, you get a notice in Hedy plus a system notification.
If microphone access was turned off, the notice says so and tells you how to turn it back on.
