Points about the main problem being organizational aside, Jira has been consistently unreliable in the I’ve 10 years of using it (both hosted and self hosted). It’s a moving target. Right now, I can’t add a comment from a mobile browser (either their mobile view or requesting desktop mode) so I have to use their mobile app, which is very poor compared to the web product, especially for teams with customized screens/workflows. Their rich text editor has consistently sucked and has destructive bugs in it. Despite being logged in, it eats comments and updates all the time with various csrf or authentication errors. Tomorrow it will be something else. We use cross functional teams so it’s impossible leverage Releases to effectively coordinate releases to software that lives between multiple Jira projects. I’d rather use gitlab issues or whatever, but in an organization with lots of products, product people understandably hate those comparatively inflexible repository-based issue management. So that’s part of Jira or any issue management system is rectifying the strategic (product, project) and tactical (engineering and support). Jira's the only one that comes close (at least that I have used for any length of time) which is why it isn’t going anywhere any time soon.
