So while I am stoked how great iPadOS 13 is, the one feature I am looking forward mostly is finally having access to filesystem on iPad (create new directories etc) and also access via SMB. I tried to access my iMac's Public directory via SMB on iPad as a Guest and while it connects there and shows all files available, when I want to copy something to my iPad (I have created new directory), I get following message: "The Operation Can't Be Completed. Couldn't communicate with a helper application." Does anyone get any idea what could cause this? Is it only some beta bug or something else? Copying from iCloud to same directory on iPad works great though.
