Question about Logitech MX Master 3

Hello all, I bought the Logitech MX Master 3. I am very satisfied with the mouse! :-) Unfortunately, I cannot use the Adobe Creative Cloud Redeem Code. When I call up the given URL from the e-mail, I only get "Invalid PURL error". I have copied the URL and typed it by hand. I also tried with Firefox, Chrome and Safari. Unfortunately, always with the same result. :-( Was anyone from the Digitec community able to use the Redeem Code? - Rockero
