A few months ago I noticed that the Contacts / Address Book list (all of which are synced the the same Apple ID) are different on my iPhone, Ipad, Mac mini, and M1 MBA. All have the latest software. Some contacts just don't appear on some devices.

Now I'm noticing that some contacts on my phone are losing their name/address contacts info -- in texts to known individuals that were in my contacts for years (both group texts and texts to 1 other person), I see only the phone # in the text message itself and I have to re-create their contact card.

Is this a bug, and/or something that others are experiencing? First time I've experienced this in 15+ years of Apple products.

I have been having a similar problem. iCloud.com syncs perfectly with iPhone 13 (changes on either are instantly reflected on the other), and will send info to M1 MBA but changes to some fields done in the contacts app in Ventura won't update to iCloud. Also, recently I have lost about a third of the data in my contacts (email addresses, companies, job titles, related people). With Apple care advice, I have reinstalled MacOS three times, even using Apple Configurator to completely eliminate any chance that data corruption in the OS or other inaccessible partitions was causing the problem. The problem continues whether setting up as a new machine without restoring Time Machine, or after a Time Machine restore. Waiting now for Apple care and engineering to get back to me. Engineering will be able to advise whether this is an OS bug that can be fixed by an update or what else we can try. I've spent weeks on trying to fix it up until now.
 
This is a MacOS bug that is being worked on and should be fixed by an update. The advice is to install all updates and test again to see if the bug is still there.
