Came here wondering the same!
If you go to playmultiverse.com/redeemyazebas, it'll accept the code, but as near as I can tell, it didn't actually add the material to my account.
I'd reach out to One More Multiverse — their company nearly shut down in the time between the book's manufacturing and the release, so there might be some glitches on the backend.
Sent them a ticket, I'll report back if they have an answer for me, thanks!
I had the same issue! I ended up joining their discord and filing a ticket, and they got it sorted for me 🙏
Have we heard anything? I'm in the same boat.
