Is there any way to reorder playlists? So that I could move "Shuffle 2" from 04 to 02 on this list?
Looking up in the Instruction: no word about it.
Looking at the playlist screen: the small bars on the right hand side are missing from the playlist items. (I mean the three small horizontal bar which is visible on the titles when you are reordering the playlist content). That means for me, this action is not foreseen.
If you do not have too many playlists, or you do not mind if they are destroyed by playing around, you can try the following:
Connect your Kann with a USB-C cable to a Windows7 or 10 PC. Without installing any driver, or maybe after an automatic driver installation, a KANN icon shall appear in the Windows Manager right side panel, under "Computer". If you click on it, you shall see "Internal storage" in the main panel (maybe "microSD card" as well, if you have one). Doubleclick on it, you see folders, one of them is "Playlists". Rightclick beside that, and create a new folder, name it "tmp". Doubleclick on "Playlists" folder. You will see .m3u files, named as your playlists.
I suspect KANN orders the playlists as they are physically stored on the disk directory structure, just in reverse order. I.e last created entry go to the end of the directory list, go to the top of the playlists. Now comes the trick, and possible destruction of playlists:
Drag and drop the "shuffle 3" and "shuffle 2" from the playlists folder to tmp folder, does not matter in which order. Check if the size of the file is not 0 after he move. Then drag and drop "shuffle 2" from tmp to Playlists folder, finally drag and drop "shuffle 3" from tmp to Playlist folder. Now you can check on the KANN, the order shall be as you wished. Side effect can be that all your playlists will disappear later. Happy hacking

Maybe there are some programs that can change the order of the directory entries direcly on the storage medium, like in old times some DOS programs - I have not researched any further.
