Yes, fans can scan in and grant permissions well before the Light Show begins. Once they've scanned the QR code and allowed camera permissions, they simply need to have that browser tab open when the show starts — their phone will automatically sync and begin flashing with the programmed sequence. This means you can promote the Light Show throughout the first half, and fans who scanned in during pre-game or early quarters just need to return to their browser when the moment arrives. They can also scan a new QR code right before the show if they missed earlier prompts.
