first it was the time remaining that went missing. now sync history, which at least showed some indication of the progress of syncing has vanished. got a message yesterday that the box that opens when you click the icon was being updated. Now today instead of sync history and activity, it shows 'your activity' and 'sharing activity' but there is nothing there. so the sync history information is no longer available and there is now ZERO indication of how far along the sync is. you just keep making the app worse and worse.
