recently, (it has worked in Cubase 11, but unsure if it was before or after the latest maintenance update), the 'Import Tracks from Project" option does nothing but return me to the arrange window. If I choose to import them into the project folder, then the sound files show up in the Pools window, but the tracks are still missing from Arrange.
Mind you, this used to work great, where I could check whole folders of sounds in tracks and import them.
