My opinion based on feature and screenshots is that the UX is as shitty as Jira. The nightmare with Jira is this product manager obsession with kaban boards that become overwhelmed once your project become serious.
This totally expected level of unconstructive critique makes this comment a miniature art piece.
Snark all you want, but that's this person's experience and it's worth considering why that is the case. I'd wager they've been a victim of productivity theatre, with management saying "we need to be agile! make it so everyone -- your job depends on it!". Then, they may even hire an experienced agile manager but (for whatever reason) give them no chance to spend time and effort properly training everyone involved in how to work differently and to use the tools effectively, and how to communicate the "burn-down rate" to the users every time-period so that their expectations may be set correctly. Combine this with the attitude of many "I'll raise it as a ticket, then I'll have something official with which to chase the developers", and it's perhaps easier to see how things can become chaotic.
Perhaps you've been fortunate enough to be employed where these things are managed better than my hypothetical scenario above, but my experience that is the exception, not the rule, so it's not surprising that people can become fatigued.
