iPhone cannot see MacBook in AirDrop

Even though my Macbook and iPhone are on the same Wifi and both are running the latest OS, I can only send files from my Macbook to my iPhone, I can't send files from my iPhone to my Macbook because my iPhone can't see the Macbook. I'm signed in with the same Apple account on both devices. I read about half a year ago about similar bugs, but I don't think it's the same error... Or is it?
