Yesterday I connected my Aura to my updated Windows 10 PC, reader not visible in Kobo app nor in Calibre. I did a factory reset, that worked; the reader was seen in Calibre, re-added all my books and I could read again.
But today I reconnected the reader and again, not recognized.
Seems a reset is a one time only solution
So I submitted a ticket with Kobo. I suppose they will get a lot of them, since MS started rolling out the update 2 days ago officially.
