Continuity Features Broken Between iPhone and MacBook Pro

I had my MacBook Pro (M3 Pro) working perfectly, until I went to a trip for a couple months. I left my Macbook turned off at home. Only traveled with my iPhone 16 Pro and my iPad Pro (M4). When I got back and turned on the Macbook I noticed that these features were not working on the Macbook anymore:

- Can't make / receive calls using the iPhone.
- iPhone mirroring: Unable to Connect to iPhone.
- Use my iPhone hotspot: Failed to enable Personal Hotspot.
- Copy / Paste (universal clipboard): between the iPhone and Macbook.

Both my iPhone and iPad still work perfectly: I can make / receive calls using the iPhone from the iPad (and with Wi-Fi calling too), use the iPhone hotspot in the iPad, Copy / Paste text between the iPhone and the iPad.
The Macbook works perfectly with the iPad in regard the above features too. The problem is only between my MacBook and iPhone.

I thought maybe it would be a problem from the Macbook, then I did set up a new iPhone (with the same apple account of course) to see if the problem persists. With the new iPhone (16 Pro Max in this case), the Macbook was working perfectly in all the above features.

Then I tried creating a new user in the Macbook, using the same apple account and my current iPhone (not the new one), and it also worked perfectly in all the above features.
So I think the problem is the connection with my apple account.

Yet, my MacBook is seamlessly syncing with iCloud (notes, reminders, bookmarks, etc), just like my other devices.
All devices are updated to their latest firmware (macOS 15.5, iOS 18.5, iPadOS 18.5).


Does anybody know what could be happening? Or how can I fix that without creating a new user or reseting my devices? any way to reestablish the connection to my apple account without login out and potentially losing data in the process?

When you log into https://account.apple.com does everything look right in the "Devices" section?

Someone else may have more specific ideas/instructions on getting that stuff to work properly again…but what I'll say is that if logging out and back in to your Apple accounts causes you to lose important data then you need to rethink your reliance on it.

Yesterday, after this post, I logged out and logged in my Apple account, to see if this was fixed and nothing. I guess because there must be some cache files that are not reseted.
At the end I decided to restore my MacBook to factory setting (set my Mac as new with my Apple account) and that fixed the issue.
Gladdly, I have everything on iCloud.
But that’s the only fix I could find.
So bad that Apple doesn’t have a fixing tool for this.
