How my notes got deleted automatically?

Hi,

If you are missing Notes, and the notes were stored in iCloud, make sure that you have Notes enabled within iCloud Settings after you have updated your iPad to iPadOS 15.3.1.

The following articles should be able to further assist:

• iPadOS 15 - Apple
• How to update to iOS 15 or iPadOS 15
• Use Notes on your iPhone, iPad, and iPod touch
• What does iCloud back up?
• Add an email account to your iPhone, iPad, or iPod touch
• About missing information after you restore your iPhone, iPad, or iPod touch with iCloud Backup
• If you're missing notes on your iPhone, iPad, or iPod touch

Hi,

Not a problem!

How did it go? Were you getting a message that your iCloud Storage is full or your device storage?

If iCloud Storage is full, it means the device has not been backing up successfully to iCloud. I would recommend upgrading your storage plan to continue having your content backed up and stored with iCloud.

• Manage your iCloud storage
• If you need more space for an update on your iPhone, iPad, or iPod touch - Apple Support

If your device storage is full, you can go to Settings > General > iPad Storage and see storage recommendations on how to free up space.

• What's the difference between device storage and iCloud storage?
• Upgrade to iCloud+

Hope this helps.
