Usually resetting Ad ID or delete Ad ID helps if the videos won't play.
Yes you are correct.
But the videos have a cut off time for daily. In my case it is 1pm, Eastern. Just as WGT does for the consecutive day bonus or when you have played. I usually do the videos in the morning, but was late in doing today. That means I will have to wait a day before I can get the 150 credits again, in the morning.
Not sure who you might of been responding to if anyone, but I normally don't have problems with the videos. But lately I have, and I even posted to Nico concerning. He responded that they have contacted the video supplier about the problem. That was 3 or 4 days ago. His response came to me at about the same time he posted on Discord concerning the same issue. But today when I tried them, they were again working correctly.
