When you restore deleted messages on an iPhone, they should typically go back to your Messages app and be available in the same location where your other messages are stored. However, if you have recently restored your iPhone and are unable to find the restored messages in the Messages app, there are a few possible reasons for this:
1. Check the time frame: Make sure you're looking within the correct time frame. If the messages were restored from a backup that was created before a certain date, you may need to scroll back in your conversations to find them.
2. Verify the restore process: Ensure that the restoration process completed successfully. Sometimes, if the restoration was interrupted or not performed correctly, the messages may not appear in the Messages app. In such cases, you may need to attempt the restore process again.
3. Check other devices: If you have multiple Apple devices (e.g., an iPhone and an iPad) that are connected to the same iCloud account, your iMessages may be synced across these devices. Check your other devices to see if the restored messages are available there.
4. iCloud settings: Confirm that your iCloud settings are properly configured to sync your messages. To do this, go to Settings > [Your Name] > iCloud and ensure that the "Messages" option is enabled.
5. Contact Apple Support: If you've tried the above steps and still can't find your restored messages, it's advisable to reach out to Apple Support for further assistance. They can provide specific troubleshooting steps and help you recover your missing messages. You can contact them by simply selecting the "Support" link on the lower left-hand side of this forum's web page.
Note: Restoring deleted messages from a backup only brings back messages that were included in the backup. If the messages were not backed up before deletion or were not included in the backup, they may not be recoverable.
