Files app doesn’t show local files
just bought a second hand iPad Pro 9.7″. I reset it, and connect to my Apple Id. When I try to send a file (e.g. a simple txt or a pdf) and I accept to open in Files app, the application doesn’t show the file.
In the left drawer I can see in the Location section only iCloud Drive and not iPad local storage.
I cannot figure out how to show it.
Thanks for any help
