Anything in particular? I first used it about 10 years ago, on prem, and am currently using the cloud version. Current edition is clunky, slow, and constantly badgers me with Rovo shit I can't disable. IMHO, it reeks of a product once built by and for technical people that eventually got dumbed down by POs to the point of being painful for the original users. Obviously I'm no longer the target user because I assume someone somewhere appreciates these changes.

I'd argue the opposite. The thing is so bloated and the simplest of things seem to be so hard. Import markdown in confluence? Nope not natively. Add an issue to the board? better go to the one workflow to do it and not in the actual ticket.

Perhaps I just haven't noticed them, which is unfortunate. I have noticed that I often have to double or triple click to open a ticket on my board. There's no reason for such a core functionality to be that slow.
