Great question! It’s super frustrating to lose important notes, especially when you thought they were safely backed up. Here’s what I’d recommend to recover those deleted iCloud notes:
First, double-check all your devices connected to iCloud. Sometimes, changes haven’t synced across all devices yet. Check your MacBook’s Notes app to see if the notes are still there.
Next, sign in to iCloud through a web browser on your MacBook. Go to the Notes app there; sometimes, it syncs differently and might have the notes. Also, check the “Recently Deleted” folder here, as it might hold notes that haven’t been purged yet.
If that doesn’t work, you might need to restore from an older iCloud backup. This is a bit drastic as it will revert your entire phone to a previous state, but it might be your only option if the notes were critical.
Good luck, and let me know if any of these steps help!
