Messages app on new Mac Studio not showing contact names, just phone numbers
I recently upgraded to a Mac Studio from an older Mac Pro (2013) and have run into a strange issue with my messages app. They used to show me everyone who is in my contacts by their name - and now only 1 or 2 contacts are showing up by name, the rest are showing up as just their phone number.
The thing is, in my computer's system preferences, under my apple ID > iCloud > I have Contacts turned ON (see below), so it should be syncing with contacts. To confirm, if I open my Contacts app on the computer, all my contacts are synced and showing up fine.
Any idea why it's not showing contact names in Messages? Thank you!
Mac Studio, macOS 13.4
