Regarding explanations... How can you explain something to those who simply don't want to understand? You share your experience, because you've been through this many times, and you try to explain everything so that people don't step on the same rakes that have caused problems for many people in the past. But there's no effect. However, if you don't explain anything at all, then the consequences of stepping on those rakes will definitely appear.

I'm answering, everything worked on the first try. I also don't see the point in trying something for the n-th time; it's not official. And what's so difficult about it? :D
