# Troubleshooting

## Camera or mic not working

1. Check browser permissions for `app.skill3d.work` (Allow camera + microphone).
2. Close other apps using the camera (Zoom, other browser tabs).
3. Reload the page and start the session again.
4. On iOS, use **Safari** (not in-app browsers).

## Voice coach will not connect

1. Confirm you have enough [credits](/billing/credits).
2. Check network (Wi‑Fi or strong mobile data).
3. Hard-refresh the app.
4. If it still fails, sign out and back in, then retry.

## “Get the app” does nothing

* **Chrome / Android / desktop:** Wait for the install prompt; if the app is already installed, open it from the home screen.
* **iPhone:** Use Safari → Share → **Add to Home Screen** ([install guide](/getting-started/install-app)).

## Visualization failed

1. Ensure the camera is live and the subject is in frame.
2. Check credit balance (needs at least 5 credits).
3. Try a clearer, better-lit frame and a more specific instruction.
4. Retry once — transient model errors happen.

## Session feels “stuck” or wrong

* Reframe the camera; ask the coach to look again.
* Start a **New chat** if the thread is noisy (archives the old one).
* End the session and start fresh if the live connection is unhealthy.

## Still stuck?
