Each court needs its own companion pass (generated on that court's Account page). Panels are remembered on this device. Do NOT regenerate a pass mid-day — it revokes the old one and disconnects the panel. ▶ Start / ■ End signal that court's phone to start streaming or stop & reset for the next match — these need the phone on the remote-control app build; older builds ignore the signal. Have the phone showing its camera view before you tap Start; each tap sends a fresh signal, so if nothing happens, tap again.
