REQ PACKS

Hi, I have a problem, when I try to open my packs or my collection, I get “Service of supplies not available”.
Can anybody help me?

Hey OP, generally this can mean there area few server issues (which there are right now). Sometimes you can hard reset your console and the issue clears up, other time you just need to wait a little before you can open them. Alternatively you can visit the REQ section here on Waypoint
