Videos synced to Android using WMP are then synced to OneDrive (and can't be stopped)
More of a design oversight than a bug. I synced a 2gb movie to an Android phone using Windows Media Player and then it tried to sync it to my OneDrive, which can't actually be cancelled on the Android client. I had to disable video syncing to stop it transferring. As it was a 2gb file it was quite a pain.
