Supposed to be given out immediately on completion, I assume it isn't and won't be given out until the end of the month? I completed 233 wins yesterday, and nobody else seems to be have given it either.

I’m sure the immediately on completion refers to the end of the month and the qualifying period has ended.

It completes at the end of the month, just like every other monthly badge.

I agree the wording "immediately upon completion" on the challenge page is a bit misleading.

It is usually implied that a monthly badge would be given out at the end of the month, but if you take that wording, in combination with the fact that for this one, unlike most other monthlies, you only need to hit the threshold number of wins and aren't in direct competition with others vying for the same goal, that will be an ongoing misconception as it is written now.

I think that immediately upon completion just means you don't need to visit the badge requirements again to get credit like the ones where it says come back here to claim the badge when you have fulfilled all of the requirements.
