Contacts disappeared after IOS 18 update.

Same and majorly frustrated with apple engineers!!! I’ve already spent 5 hours with ‘senior’ support only to find out they can’t help me. I’ve been backing up daily to iCloud for 2 years and there are only 10 backups to restore from? Wtf is that? I pay for 2TB of Icloud and am only using less than 500GB. I was able to recover some but not all from a backup a week before I updated. To make matters worse, when I use siri to place a call to a contact, it brings up the correct contact information but connects me to an entirety different contact. Talk about road rage when you're hands free doing 70 on the highway! At some point I was asked to RESET MY IPHONE and recover from backuo only to find out I had lost every account on MS Authenticator. GRrrrrrr! I'm on a 14 pro and it's now sluggish as h3ll with crashing apps. What a huge disappointment 😩 Senior support person let me know they don't even use contacts and prefer the Google contact manager! Where did 2 years of backups go?

My contacts are messed up too, after the 18 update. I have contacts from five years ago but not recent ones. Wth! All I did was do the update and this happens. Aren’t the updates suppose to be tested first? I’m surprised at Apple. I hear there’s no fix?? I’m very disappointed.

IOS not only wiped out ALL of my contacts on my main iPhone, it wiped out ALL of my APPOINTMENTS.

I am not going to update my two other iPhones!

Your contacts and appointments are likely tied to one of your email accounts. Are your email accounts installed on your device and up to date?

You might have accidentally turned off contacts in the icloud.

IOS 18 wiped out my contacts on my iPhone and my iCloud account.

I didn’t turn anything off I just applied the update.

From what I’ve read there is nothing Apple can do to fix the issue.

What type of device are you using when looking up your account? Maybe try changing devices or resetting phone.

Thank you! Signed into all of my mail accounts and my contacts are back!
