I've created two new jira workspaces, one from my personal email and one from my corporate email. For both selected Scum template to start with (to play with settings, options, etc.), both are on premium trial.
But I get 2 different versions of UI - for personal account it looks like Jira always looked like in other workspaces (Planning vertical section on the left, image 2) and for corporate one it looks like horizontal tab bar (image 1)
Is there a way to change this?
