I've read it and I plan to ran it as a one-shot next Friday. I hope to find the time to work a bit on it before the game as I find it a bit weak, even though I like the general idea and the map.
What worked for me was to get the redemption code from the D&D store and insert that into D&D Beyond. Nothing seemed to happen, but if I then looked the adventure up while showing all the sources, I had access.

I hope that this product will be offered for sale separately at some point in the future. I'm not backing this campaign, but I would be interested in this.
As far as I know there are no D&D products for which the IP is not 100% held by WotC. Gygax and Arneson has some leftover interests with TSR, but WotC liquidated them more than 20 years ago.
Is is certainly true that some products disappear without explanation. S1 Tomb of Horrors was gone for...
