Either I am missing something or their documentation is seriously out of date. which is super frustrating.
Find issues in a company-managed project
To find issues in a company-managed project:
From your project's sidebar, select Issues.
Select a pre-set filter in the sidebar, set the field filters, or both.
Order and sort the issues using the options at the top of the list of issues.
Select an issue to view or edit it.
-This is NOT true. There literally is NO “issues” button on a JSM project sidebar.
Enable the project issue navigator
The project issue navigator lets you view a list of the issues in your project, and filter them to find what you need. You can search for one or more issues using the text search field and built-in filters.
To enable the issue navigator for your team-managed or company-managed project:
Go to Project settings > Features.
Toggle on the switch for Issue navigator.
You can toggle this feature on and off any time without affecting any of your project’s issues.
-this is also not true. I am in the features setting now on my JSM board and this is not something available to turn on???
