I posted this last week
It looks like there's a bug with FREEDDO2024. After you redeem the code, look in the Transaction History. Two of the items in the list for the code are ModuleBlades and ModuleDragonborn. Then look in the store for which Adventure Packs you still have available. On a new account that didn't redeem any of the previous free content codes, I still see
Dragonblood Prophecy and Secrets of the Artificers as available for purchase even though they are supposed to be included with FREEDDO2024.

In the end, I opened a ticket. They sent me a new code for the 2 missing items (which didn't work until after today's server maintenance) and it added those 2 to my account. I've asked if I can share the code or if they want people to open a ticket, but I haven't heard back yet.
Keep in mind that they may have fixed the FREEDDO2024 code for people who redeem it since they became aware of the problem, so it might work fine now.
Note that these 2 items were included in all of the previous free content codes: DUNGEONCRAWL, DDOQUESTS2021, and DDOfreequests so if you used any of those, you already have them. For anyone who is wondering, FREEDDO2024 and DUNGEONCRAWL appear to have all of the same content.
Also, to clarify, Secrets of the Artificers is an adventure pack and is included in FREEDDO2024. Vaults of the Artificers is a challenge pack and is not in FREEDDO2024 (or DUNGEONCRAWL, but
was in DDOQUESTS2021, and DDOfreequests).
