To anyone still having issues I would recommend:
- Sign off everywhere (FaceTime, App Store, iCloud, etc)
- Sign back in and make sure the email is the same everywhere (if you sign in using @gmail on one place and using @icloud on another won't work, even if it's connected to the same account, this is what brought me problems earlier).
- Restart devices with everything set up properly
Keep in mind pairing the devices via Bluetooth is not necessary, just make sure Bluetooth and WiFi are turned on on both devices, and connected to the same network.
