Some users of older versions of Autodesk Sketchbook on desktop report seeing a message “the webpage cannot be found” in place of the log in screen they used to see.
Sketchbook spun out of Autodesk as an independent company in 2021, and Autodesk no longer supports these older versions of the app. It appears that the servers that supported the log in feature were shut down in early May 2024.
The current version of Sketchbook Pro is available on the Windows Store and the Mac App Store as a one-time purchase (not a subscription). As an independent company we continue to support and update this version of the app.
