AirDrop to different devices instead to "contact"
Hi Apple Community
My friend and I both have two iOS devices. She uses her Apple ID on her devices, I use my Apple ID on my two devices. Now we'd like to share photos. When she wants to send her photos to my iPad, she can only see my profile/me as a person in the Airdrop menu, but she can't choose the device (my iPhone vs. my iPad). Same problem the other way round: I can see her as a contact, but I can't choose to which of her two devices I want to send the photos.
Why not? Are there any system preferences to change this? Any ideas?
Thanks for your help!
