Hi there
Please try this
Sign Out and Back In:
- On your Mac, go to System Settings, click your name (Apple ID), scroll down, and select Sign Out.
- On your iPad, go to Settings, tap your name at the top, scroll down, and select Sign Out.
- Restart both devices, then sign back into your Apple ID on both the Mac and the iPad. This forces your local keychain and iCloud session to re-authenticate properly.
Verify Wi-Fi and Bluetooth: Ensure both your Mac and iPad are connected to the exact same Wi-Fi network and have Bluetooth turned on.
Check Handoff: On your Mac, go to System Settings > General > AirDrop & Handoff and make sure Handoff is enabled. On your iPad, check Settings > General > AirPlay & Continuity.
