Tags and even if I start from a video and use the "run a video party" menu option, and when I finish the live session I share them in their respective pages. On the first page, but surely it's not so, facebook tells me that it cannot start it. I suppose that I have the same setting in both pages, However, I have two similar pages, I havent' the video party option when creating a post, I'm able to run a video party in the page: when I create a post I have the video party option. On the second page, I've created them as community pages. I'm publishing live videos on both pages, since the behaviour is different... What setting could affect the possibility to start a video party?
