Have done watch videos on carousel every day, no problem. Have tried the watch videos above the carousel & and they are not worth a crap, I have yet to collect 1 credit, no way to collect them!, even when they say done.
They've worked fine for me... not like the videos, you're getting actual credits, not 'views'.
I love their positioning. You can play them and the carousel ones together to save time.
I've been earning credits by watching videos for 5+ yrs. I just 90 reads when I got a popup stating that my browser need to accept 3rd party cookies in order for me to watch videos. Actually, I lost 95 reads as I didn't get the last set that I had just earned.
