Unable to find custom Issue Screen Scheme for project

[Justin Landis]

Hello everyone,

I have made a custom issue screen Scheme called "Sample Issue Screen Scheme". I am trying to associate this screen with a custom project, however after navigating through "project settings" > "Issue types" > "actions" > "Use a different scheme"

I am not seeing my Issue Type Scheme in the list of "existing issue type scheme"s. Am I missing something crucial?

I'm not sure if it matters but I'm currently on the free trial of Jira-software but this particular project I am trying to link is a business project.

I found the problem, I needed to go to "project settings" > "Screens" >"Actions" > "Use a different scheme".

Can anyone explain the difference between the schemes managed in the "Issue types" page versus the "Screens" page?
I guess more specifically, the difference between "issue type schemes" and "Issue type screen schemes".
