Sidecar not connecting Mac to iPad as second screen
Sidecar needs both devices on the same WiFi network, both signed into the same Apple ID, and both close to each other. Check those three things first. If they're all set, restart both devices.
Sidecar lets you use your iPad as a second display for your Mac. When it stops working, it's because the devices are on different WiFi networks, not signed into the same Apple ID, or too far apart. We'll check the network and Apple ID, then restart if needed.
