Contacts - Duplicates

I just fixed mine by loggin to iCloud, Settings, Restore Contacts and selected the last backup before installing Big Sur and I got my contacts corrected. Hope this is helpfull.

Please see: If you see duplicate contacts after setting up iCloud Contacts - Apple Support.

I just logged into my iCloud on my computer and went to my Contacts. Instead of having "All Contacts" selected, I chose "Card". That automatically eliminated all the duplicates

• I have experienced the same problem, but I have upgraded multiple computers to Big Sur--so I now have four copies of each contact in my iCloud contacts (on all devices, as well as the iCloud web interface.)
• My initial search took me to If you see duplicate contacts after setting up iCloud Contacts - Apple Support. But the "Before You Begin" section of that site says, "If you see duplicates in Contacts on iCloud.com, visit Apple Support for help." When I went to Apple Support, this looked like the most relevant post, but the only answer was to go back to the page that sent me to Apple Support.

I have duplicase contacts too after upgrading to Big Sur. And I haven't being able to fix it yet. Have you find a fix? Thanks!
