Our team uses one central board on an existing project (Project 'B') to track the work across multiple projects (Projects C & D). Recently we have been tasked with starting a new project, for which we created a new project 'A'.
The issue comes into play while we were building out the scope of Project 'A'; while the initial set of stories were created directly within the project, a number of additional issues that were needed were created from our scrum board, which lives within Project 'B'.
During issue creation we were sure to assign them to Project 'A', and we assumed this was successful as the issue prefix indicated the correct project; but when navigating to Project A's backlog, none of the new issues are showing up.
What am I missing?
