Hi there! Relatively new to Jira, trying to improve existing service desk set up. Right now stuck on trying to understand the whole issues, fields, screen and schemes configurations. I understand that they are interconnected, but can't fully figure out the way in which they are connected. Every time I tried to change something (i.e. remove a field from customer view), I end up breaking something else. Is there an article/tutorial/video that can help me better understand how it works? I read quite a few articles in Community and Documentations, but non seems to cover the top view. Any help appreciated!
