“Thank you for the message. Please note that videos are region based with a certain number of views available before it is removed from being available. Once a video has reached its required view count it would no longer be available. These videos are typically updated ever 2-4 weeks by the 3rd party that provides these offers. I would suggest checking every so often to see if any new videos are available in your area to redeem.”

“Thank you for the message back. You would want to contact the 3rd party that hosts these Free Credit Videos regarding why they are not offering as many in your area. Unfortunately we do not control where these offers are available”
My conclusion was correct:
The adds are region based, they are limited and WGT is ok with it as it is.
