Not all of Part 1 is currently available. At the moment, just 1.1 and 1.2 are available. 1.3 should be out in the next week or so and more content continuing to come. By the end of the Early Bird Access period all of Part 1 will be available.
I am adding in some “Coming soon” notices to make this more clear and should have a newsletter update going out this next week explaining more of this.
My apologies on the lack of communication here and thank you for your patience while the rest of Part 1 comes together.
