i'm evaluating those products and wonder what am i doing wrong, i found a lot of tutorials and documentation with nice features.. but once i start the try cloud version, i can't do anything att all, not even make issue for an epic or drag from a product / buglist to a kanban board ??? i just can't find my way and documentation seems to be written for another product... tells me to activate kanban backlog by clicking on the "more" button... where is that button ???
My guess is you've been reading documentation for Jira Server and not Cloud.
The two have very different front-ends now, and although a lot of the underlying principles are the same, they're different products. With most of the docs you've been reading, look to the top right and make sure the "cloud" button is selected.
