I just checked it and see I also have the December 2023 NFT 😀
You only had to claim once to receive it.
I see there is also a referral reward. I think I might spam my referral code some more to get this one too 😄

That’s awesome! Yes once is enough to get.
The referral NFT is the one that I failed to get 😂 maybe I not good at convincing people to use my referral code 😂
