I installed Premium Pass and all the related content, but it's not showing up in game.

Does anyone know what to do, I am at my wit’s end! I went to play it yesterday too, and it’s led over from then. All the DLC guns are locked to me, but I own all the dlc that they are part of! Help!

Unless I’ve misunderstood (quite possible) you need to unlock DLC guns via assignments as they are not just given to you. If you mean that you can’t unlock them by doing the assignments or they were previously available to you but are now locked then that’s a different matter entirely.

Did you have them before ? I had 2 re install premium a few times before check if it’s still installed

I had already unlocked quite a few of them beforehand, but the game won’t let me use them.

I did. Did you have the same issue as me? If you did,how did you fix it?

OK I get you now. There are a few things which can cause that, such as DLC uninstalling themselves and so on, and it might be worth opening a ticket with EA support.

It’s been a while since I’ve played on my Xboxne, but in addition to reinstalling the DLCs did you reinstall the premium file as well? If that is missing or corrupted during a title update generally you can’t access the expansions or DLC weapons if memory serves me right.
