Again I will reiterate - These videos are still Token offers. The fact that the requirement for the reward is to watch a video does not change that fact. There has never been a dedicated "Watch videos for Tokens" button of any kind. If a particular provider's wall shows something like that, then that would just mean they may forward a video for the user to watch in exchange for a Token reward. That, again, is an offer for free Tokens.

To give an example - In my case, the only provider who has a dedicated section/category in their offer wall for videos (labelled Videos), is Superrewards. Never seen an offer popup in that queue though.
