Sync immediatly if User add large number of files.
In case if user add large number of files to onedrive, sync is performed in the background by onedrive application. This is very slow and have issue where some of the files are lost as user may have restarted many time in between. I think in case of user add large number of file, onedrive app should sync immediately and block the user. This will avoid adding lot of unnecessary issue and changes of losing file.
