Since when? Are we talking post updates or what? I mean if Airdrop works that's good, it doesn't for everybody. What macOS and iOS are you on now?
Currently I just use the Share button on my iPhone for everything, my MacBook is always first on the list if nearby. If not, I share to email and send to myself using a different email address. What happens when you do that?
The Share button is the primary way of "sharing" images, files, notes ect between apps and other users on the same WiFi network and more. It looks like a square with an UP arrow, as below.

When pressed it gives you a range of options, usually your devices, people you have recently contacted by social media or SMS as well as a scrollable list of actions like Copy, Print, Save to files, Assign to contact ect, ect.
