We use Jira tickets to track customer bugs and feature requests, although we do not use service desk and are not interested. Given that, this is for internal usage only.
1) How do you dynamically tie tickets to customers? We use comments today, which is manual and difficult to search if users use acronyms. We use salesforce but have had endless problems with our connector to Jira
2) When a bug, for example, is fixed, what is the best way to get a notification of that, along with all customers tied to that ticket?
