I'm not sure at which beta it happened, but somewhere during the iOS 26 Public Beta releases, my iCloud Contacts have duplicated close to 100 times each. When I scroll to the bottom of the list to try and manage duplicates, it indicates I only have 2 duplicates. I should be sitting around 350 contacts and instead, I now have over 10k.
Anyone else with this issue? I have filed Feedback in the app. I'm not certain if it was related to iOS 26 or iPadOS 26 as I have both, but noticed it first on my iPhone. I confirmed that the issue has affected my iCloud Contacts and therefore all of my Apple devices included older iOS and MacOS versions. Short of manually deleting all the duplicates, I'm at a loss as to how I can correct his.
