Using 1P on iPhone, I used the advanced settings to backup my vault. Synced with iTunes (current version) on Windows PC (v 8.1) and I can see that 1P created a backup folder in the file sharing section; however, it appears that the folder is empty. If I right click on the folder (or left click for that matter) I should be able to copy the backup file, but clicking on the backup folder does nothing. If I try to move the whole backup folder, it indicates that it will copy, but it does not. I tried deleting the backup, performing another backup, and re-syncing, but still the same result. How can I fix this?
