There seems to be a bug in the latest version of the iOS app (have checked on iPhone and iPad). When saving a file to Sync (e.g. saving an email attachment), there seems to be a limit on how many subfolders you can navigate through before choosing the folder you want to save into. e.g. the folder structure is as follows: year/project name/development/script/ I want to save the attachment into the script folder, but I'm only able to navigate into development. This wouldn't be a huge problem if you could move files...
