iCloud Information Not Syncing Correctly Between Devices (Contacts and Messages)

Hi, I have been having problems with some iCloud information between my iPhone 15 Pro, iPad Air (M2), and MacBook Air (M2). Specifically, I am having trouble with getting my messages and contacts to sync between devices. I have all iCloud sharing services enabled for all of my devices. I have tried turning them off, restarting devices, then turning them back on, which doesn't work. I also have tried signing out of my iCloud account, restarting the devices, and then signing back in. This occasionally works, but only to update the contacts and messages to the moment the device is re-added to my iCloud account. Any future additions to contacts do not sync but I continue to receive messages but sending them sometimes doesn't work unless it is from my iPhone. I have checked and made sure that all of my receiving/sending addresses are the same across devices and that I am signed into the same iCloud account. My iPhone is the only one that is current/up-to-date with the correct contacts and messages. How do I fix this?

Since you've already toggled the services and signed out and in, here are a few things that often fix stubborn Contacts and Messages sync:


All devices need to be signed in to the same Apple Account and be on current software. For Messages, check Settings > [your name] > iCloud > Saved to iCloud > Messages in iCloud on the iPhone and iPad, and Messages > Settings > iMessage > Enable Messages in iCloud on the Mac. Tap Sync Now there after enabling it.


It can take a while for a big message history to catch up, and your devices need to be on Wi-Fi and plugged in for it to finish.


For Contacts, make sure the default account on each device is iCloud (Settings > Contacts > Default Account on iPhone and iPad). Contacts saved to "On My iPhone" or a different account won't sync. You can also check iCloud.com/contacts: if the missing contacts appear there, the problem is only on the device, and a restart or toggling Contacts off and on in iCloud settings usually fixes that.


Apple's page on this is https://support.apple.com/en-us/102651


Which of the three devices is behind, and are the missing items there on iCloud.com?

Correction: the link I included above (102651) was the wrong page, sorry about that. These are the right ones: Set up iCloud for Messages on all your devices: httpshttps://support.apple.com/en-us/HT208532 up Contacts with iCloud: httphttps://support.apple.com/guide/icloud/set-up-contacts-mm2e5b1c6686/icloud you can't create, import, edit, or delete contacts: https://support.apple.com/guide/icloud/create-import-edit-delete-contacts-mmc1cd5b86a1/icloud
