Going Live

I am having an issue going live on zoom and I am not able to call or contact anyone from zoom.

I am able to hit the 'Go Live' feature, however I want to live from a particular page that I manage, but I cant.

I clicked on go live - put in all the details - went down to where it says go live from timeline, page or group - clicked go live from page - and only one of the page I manage appears which is not the page I want to go live from. Does anyone have any idea how to resolve this issue?
