The biggest issue, in my experience, has always been its performance. Perhaps I have only worked in organisations that have completely misconfigured their Jira instances or the servers are underpowered, but even with the Atlassian Cloud, I am used to waiting 10 seconds to move a ticket from one column to another. Or add a ticket to the backlog, click the backlog, ticket isn't there yet, refresh the backlog, it's there. Add a ticket to the sprint, click the sprint view, ticket isn't there. Refresh the sprint view, it's there. This sh*t. Every day. Is driving me insane.
I don't want the perfect tool, just one that isn't horrendous.
