macOS isn't made for two accounts using the same Apple Account
I use a macOS device with two users: one for work and one for personal stuff. With this I can simply switch context without being distracted by the other things. During working hours I don’t watch YouTube, in the evening I work on my own projects or watch YouTube.
Both accounts are connected with the same Apple Account since I need notes, calendar, iCloud Drive and especially my developer account. When setting this up you almost immediately know this is not how you should use macOS: both accounts share the same user profile picture.

Recently I noticed something worse:
When logged in with both accounts, files sent via AirDrop will be transfered to the non-active account. I was unable to share files via AirDrop (from my phone to my Mac) to myself being logged into my Mac. I found the files in the other user account that was locked (but logged in). The whole evening I asked myself why AirDrop wasn’t working even though the iOS UI indicated a successful file transfer. Now I know. Apple please fix.
