where did the option to follow/bookmark stories go?

I normally press that option for some stories, but it's not there. Admin, where is it?

https://www.mycast.io/bookmarks - all stories and people

to follow them, - click on every story/person a bookmark sign right above

Am I wrong?

no, you're right

I've also noticed that you can no longer view new stories beyond one page.

I wonder why they're gone
