Limited edition problem

Hello, I’m not a very active xbox member, nor am I smart in any technical areas.
However, I’m a massive Halo fan, and I bought the limited edition recently.

When I bought the limited edition, I installed the disc 2 multiplayer dsic, and then entered my codes.
I later read on the codes “Early access ti 6 unique specialisations” - “Can be used one at a time, starting at level 50”.
Does this mean I have to wait to lvl 50 to access the specialisations, even though I bought the limited edition?

Thank you in advance. Personally, if you’re going to post an answer, I’d prefer it “You have to wait until lvl 50” or “You have a problem, and of course the problem”, you guys don’t need to go into complex detail, because it’s doubtful I would understand it. Thank you.

You will have to wait till you reach SR50 then you will be able to pick one of the other specializations and level that one

In short. Yes you will have to wait till 50 even tho you bought it.

Those who didn’t only have access to 2 of those specializations at the moment and they have to level to 50 as well.

Thank you very much.
