So LSK stole the show for Waves with an inferior product, and after 4+ years now, the better platform is getting ahead now.
I have marked the important parts in bold.

I cannot access my waves inside my Nano Ledger - The exchange app which I've installed on Windows 7 does not see the Ledger or anyway does not offer me the chance to "import account" as outlined in instructions. WTF? The process should be a no-brainer and yet I'm stuck for one hour already. This totally sucks.
Any ideas?
Did you do it as described here?
