Before you write

Most problems are solved by one of these:

  • Device doesn’t appear? Make sure both are on the same Wi-Fi, turn off any VPN, or connect with a room code (Nearby devices → New private room).
  • Transfer stopped? Keep the page open and the screen on until it finishes, especially on iPhone.
  • Step-by-step help: see our guides and the FAQ.

When reporting a problem, tell us both devices and browsers (for example “iPhone · Safari to Windows · Chrome”) and whether you used the same Wi-Fi or a room code. It helps us fix things faster.
