Perhaps that's why the rules of Questions & Support, that everyone ignores, say "don't ask how long it takes". Because it depends.
Yes, I know. It took me long enough to get one little change into the official FAQ, and by that time it was already obsolete. Worse, I missed a spot, so now the text says two different things. But it's a basis for conversation! That's the point of skimming the textbook.
I can't comment on itch.io's communication policies, mostly because I have no idea why our admins communicate so little. But they said this many times: please don't wait around. Please don't rely on being indexed. But people don't like to hear that, even after they do read the FAQ.
