I had this issue for many many months. I have finally found a solution on my own, and it actually solved a lot of other issues I was having.
So, it appears that for *some* iOS user profiles, they are glitching out with appleID logins. I noticed on my laptop that I was unable to log out of my appleID (even going into appleID on browser and disconnecting my computer did not clear the appleID from the user profile).
What I ended up doing was creating a fresh user profile and logging into my appleID on that one. I transferred all of my files and such to the new user profile (took some time to get everything set back up) but it solved two major problems I was having:
- airdrop works perfectly every single time now, both to and from my computer and my phone;
- I was having major issues with internet connectivity. My laptop would randomly drop internet connection, even while connected to the network with no network issues and no problems with any other device. Only restart would fix these internet issues (and only sometimes). Usually I just had to wait for hours and restart multiple times to get it to work again. Now, not a single internet connectivity issue since switching to a new fresh profile.
I am not sure what happened to mess up my user profile - my guess is maybe a the backup I set up my new laptop with was corrupted. Maybe it was an issue with Sonoma and certain profiles. Who knows. It does seem like there have been others with the same appleID/user profile issues with Sonoma though.
I was pretty shocked that just this one change fixed pretty much all of my issues though, so I wanted to share it!
