How to use AirDrop on your iPhone or iPad - Apple Support

Hello, do go through this process it might help you out:

• Check AirDrop settings: Make sure AirDrop is turned on for both devices. You can check this by going to Settings > Screen Time > Content & Privacy Restrictions > Allowed Apps. If AirDrop is set to Contacts Only, you'll need to change it to Everyone. 
• Check your devices: Make sure both devices are unlocked, up to date, and have Wi-Fi and Bluetooth turned on. 
• Restart your devices: Restarting your devices after making changes to your settings can help. 
• Move your devices closer together: Try bringing your devices closer together. 
• Reset network settings: Resetting your network settings can help.

Alright kindly do that and let us know if it works. Thanks
