How do I add the Playbox overlay on mobile (Streamlabs app)?

To add the overlay on a phone, open the Streamlabs app, go to Scenes → Layers, and add your event’s overlay URL as a custom layer. Step by step:

1. Open the Streamlabs app, you’ll land on the main screen.

2. Switch your phone to landscape mode before starting, Playbox graphics only work horizontally; vertical mode is not supported.

3. Tap the menu icon (three lines, top-left) → Scenes.

4. Go to the Layers tab → tap Add.

5. Choose Add Custom Item → Add URL.

6. Paste the overlay link copied from your event’s streaming settings, done.

⚠️ Start strictly in landscape. If you start in vertical mode, YouTube treats the stream as vertical and the overlay graphics display incorrectly.
