User Profile

I have a user that can't paste text into textboxes in my app using the keyboard (Command + V) but they can do it using right mouse click and the context menu.I can't reproduce the problem because in my version of the app and also when running it in my development environment it works fine.I haven't been able to find anything on the subject in the Apple docs or via Stack Overload or Google.Does anyone have any ideas of what I could look for?

I'm looking to get my iOS app to cache file data in a place where the user cannot access it directly but it stays cached until the user chooses to clear it.The ideal solution would be to a place where it appears in "Settings > iPhone Storage > AppName > Recommendations" even though I already provide a mechanism to clear it from within the app.At the moment I'm caching the data into "/var/mobile/Containers/Data/Application/EF5B1643-C28D-4D0B-8DC6-23FFF1BEE4B8/Documents/../Library/Preloads" but it seems to intermittently get cleared by the OS.Looking at the following document https://developer.apple.com/library/archive/documentation/FileManagement/Conceptual/FileSystemProgrammingGuide/FileSystemOverview/FileSystemOverview.html this seems to be a valid location that shouldn't be getting cleared automatically by the OS.Where should I be writing cache files so they:1) Are not directly accessible to the users2) Appear in the Settings > iPhone Storage > AppName > Recommendations section3) Stay cached until the user specifically chooses to clear them (either from the app or the Recommendations section) and are not cleared automatically by the OS4) Are not backed up by iTunes or iCloud
