Hi.
When I want to try to speed up a boost by watching a video (playing on a Kindle Fire), the video option is grayed out and I can't choose it, but I can on my iphone. Also, on my iphone, if I click the "free gold" button, I have 2 options: other offers and video offer. On my Kindle Fire (where I mainly play), there is no video offer option.
Why?
