iMessage issues after iOS 27

Since updating/restoring my iPhone 14 Pro to iOS 27, Messages has been glitching. Some Messages disappeared even though I had an iCloud backup and an encrypted PC backup.

Now, when my phone is offline and reconnects, incoming iMessages may appear in notifications but not in the conversation. It affects multiple contacts, and restarting the phone fixes it temporarily. I’ve already tried Airplane Mode, restarting, toggling iMessage, and checking Send & Receive.

I suspect a Messages/iMessage software or database issue after the restore.

iPhone 14 Pro, iOS 27

Hi there

Please try this

Re-trigger iCloud Sync: Go to Settings > [Your Name] > iCloud > Show All (under Saved to iCloud) > Messages, toggle it Off, wait a minute, and toggle it back On. This forces the local SQLite chat database to rebuild and pull missing thread histories from Apple’s servers.

Deep Reset iMessage & FaceTime: Go to Settings > Apps > Messages (or Settings > Messages), toggle iMessage off, then do the same for FaceTime under its settings menu. Restart your iPhone 14 Pro, then turn both iMessage and FaceTime back on to re-establish a clean token registration with Apple activation servers.

Verify Send & Return Routing: In Settings > Apps > Messages > Send & Receive, make sure your correct phone number has a checkmark and isn't greyed out or overridden by an email address. If it is glitching, sign out of your Apple ID at the top of Settings and sign back in to refresh authorization credentials.

Thanks. I’ve actually already tried the iCloud Messages toggle, iMessage toggle, Send & Receive checks, Airplane Mode, and restarting. Restarting is the only thing that temporarily fixes it. The issue comes back when I go offline and reconnect, so I’m trying to find a fix beyond the usual sync/activation steps.

This is also happening for me on my iPhone 15 pro. The only way I can find the messages is on my mac, but I have to know that I'm missing a message.

I've tried the deep reset of imessage and icloud to no avail.

I began experiencing this same issue during an iOS 27 beta and was hoping the final release would address. I have tried all of the suggestions and sometime it will temporarily resolve the issue but ultimately comes back and nothing shared to date resolves the issue. I am using an iPhone 17 Pro Max for reference.
