I didnt realized that for this batch of twitch tokens you have to use CC codes to get 50 for a tank

I reviewed streams from 2 days ago on 2 or 3 CC’s. On each one 1 code was not working, but 1 was

So I activated 2 codes, one from each CC. The redeem page said that it gave me 4x access to a mission but one hour later, I’m ingame and I dont have any missions at all

Are they actually expired and the redeem page “lied” to me for whatever reason or am I missing something ?
