Saving the Operation:Variant rewards to skip 32 tiers on the Challenge pass

On the first operation:variant, I noticed that the last reward given after season change, and claiming it will count toward challenge pass progress.

I save the week 4 reward, and claim it together with the week 5 reward, and it still works. So it's possible to keep challenge tokens in the mail and use it for future challenge pass 🤔 (Just keep an eye on the token expiration)
