When transferring ownership of folders, there is no warning message that it will take some time, and no warning that it will make those folders/files inoperable until every folder has been successfully transfered to a new user.

Can we please add a warning that ownership changes to folders will sometimes take days depending on the file size, and that none of the files/folders can be used until the ownership transfer is complete? Not having this warning caused 4 days of downtime for my company.
