Hi @Lorelle_Deguara ,
Welcome to Community!
Yes, you will be able to pull different jira stories from different projects. Note that create filter includes different project stories and make use of this filter to create scrum board. Once the scrum is created, you manage your backlog and sprints.
As you mentioned it is not working, can you please know in details what is not working? For example, only few projects stories appears in board or no stories appears in board.
