Not seeing Issue Navigator under Project Settings>Features

Hi @Darryl Cephas , Welcome to the Community!

I can understand your confusion on this. 😊 The issue navigator is what they call the new "grid" of issues and it gives you a lot more flexibility to work with multiple issues at once (for example). If you click Filters > All issues, that's the issue navigator. And if it opens in Basic search mode, you'll have several filter drop-down menus along the top; if it opens in JQL search mode, that's your Advanced search mode. Here's Basic search:

Here's Advanced (JQL) search:

You would then click the 3 dots (...) menu above the Basic | JQL buttons and select Bulk change all 'x' issues (which is counterintuitive if you don't want all of them), then select the issues you want to bulk change and select the action you want to take. Hope that helps!
