Some of my recent memos are gone

Hello future9527 

You lost your current note, so you asked us how to recover. You must have been very embarrassed by the unintended loss

For iCloud notes only

You can check if the memo has been restored after going to Settings> Accounts> iCloud> Memo on/off. (Including recently deleted items)

After logging into the iCloud.com website with the same iCloud account, you can check if there are any notes

If you were using a memo using mail linking rather than iCloud, you may need to proceed according to the following

Tap Settings> Password & Accounts> Added email items to turn on and off the memo items as above. > Verify that the notes have been recovered since

If it still does not come in, you can check if the memo item exists after accessing the added mail website

Please refer to the link below

If you're missing notes on your iPhone, iPad, or iPod touch

If that doesn't work, you can contact Apple Support for other options

I hope the problem is solved well
