airdrop
The Airdrop on my MacBook Pro (Mid 2015) running El Capitan (10.11.4) recognizes my iPad Mini (2nd gen.) running iOS 8.1.2 but doesn't recognize my iPhone X running iOS 11.2.
The Airdrop on my iPad recognizes my MacBook Pro and my iPhone X, and my iPhone X recognizes only my iPad Mini.
Obviously something is wrong between my MacBook Pro and iPhone but since they all are recognized by my iPad Mini I'm sure it is not an issue with the connections (Bluetooth, Wi-Fi, Do Not Disturb, etc.)
I tried already reboot and restart of my devices.
I would appreciate any help regarding this problem.
Thank you in advance.
