iCloud Apple ID repeated lots of notifications about new device.

I reset my old Macbook Pro and logged again with my Apple ID, and on my main Mac device, I'm received lots of this annoying notifcation every 5-10 minutes.

I already have:

• Click on Approve
• Click on Decline
• Logged out my Apple ID from old macbook
• Remove my old Macbook Pro from my Apple account
• Restart my Mac
• Change my password
• Update Apple ID Settings

None of these options above worked, and I still get this annoying and repeated notification.

I search the forums, some people with similar problem, but no solution found.

Anybody from Apple can help with it?
