Not working for me, I rarely had any even a few months ago, and now I have none. But at a certain moment before, I could play those videos almost daily. There was also a peculiar thing with those videos during the first hour after noon (and after midnight, I suppose) – I could sometimes play those videos multiple times for a reward and then it would reset. And then, after 1 am and 1 pm, it would stop resetting and say that the reward is received. It didn't always count toward the reward, though, this bug. Sometimes you could watch 10 videos for the same reward and end up having 3 of the same, the other views not counting, I suppose. Although you did get the 'Thank you' window upon watching.
All in all, it's bugged and some people never see even that
