Glad to see you've got your rewards and they didn't poof out of existence. For most cases like this though simply restarting the game will credit the items towards your account or giving you the containers to open again.
I opened it and it went to the animation but it never showed any rewards and when I looked around in case I still got a reward I found nothing! Please help since weekly crates are hard to get!
Thank you whoever gave it!
