This question already has an answer here:
Quote from "Community Promotion Ads - 2017":
We reset the ads once a year, every December.
And another one from it:
It is a bit late into this new year, being that we're already in the second month, but we are now cycling the Community Promotion Ads for 2017!
My question: please reset / cycle the community promotion ads from 2017, ideally by ... yesterday.
