I've agreed to the NDA and invited friends, but I don't have the Preload in "My Games" anywhere. Hopefully it's just taking a bit to show up; I only worry slightly as my download speed can kind of be atrocious haha. Excited to try it out!
EDIT: Got my Pre-load going! Just took a bit to show up after-all
It may take a few hours for it to show up! If you don't have it after 24 hours, [contact Ubisoft Support.](support.ubi.com/Cases/New)
