Thank you for replying, I feel better knowing that this is a bug.
But what should I do if I've send a request to the support and waiting for more than one month for it's response?
Write again with a new mail and point out, that the popular sorting algorithm still did not recover, whatever affected your game. Because that is what should have happened after a week or so. Even if you missed out completely on some days or weeks of popularity metric, it should have recalculated at a higher place by now.
And do not focus on asking questions. Support usually does not answer questions, according to lots of threads here.
The two games without cover I mentioned, they did change position. So a recalculation happened. But your game is still on bottom of adult furry horror.
And if you only use horror furry, there are games below your game that look like they are affected by the same bug.
Since your game is indexed and you obviously have recent and old "popularity", this can only be a bug. There are games below your game with even more ratings, so your game is not the only one.
