Although they don't always load rewards at 7AM anymore, they often do. So I'd try refreshing from 7AM but if you don't have any luck after about 1/2 hour, give up and try the next day. That's usually when I have the most luck. I personally didn't care for Ka and think Love is a much better show, but it's a matter of personal preference. Hubby and also each got a 4th reward this time by popping the bottle a few times.
