Deleted Note Folder
I misplaced a note folder and can't retrieve it
iPhone 11
Where were the Notes? See the pic below. You will get your answer
The recently deleted folder will exist only if you deleted Notes from iCloud or from the "On My Phone" Folder. Deletion from other Folders does not use Recently Deleted Sub-Folder.
Please see the following pic which is self-explanatory
