Disclaimer: I'm pretty new to blender, most things I say are mostly based on observations.
So I was trying to make a Smoke + Fire simulation in Blender 2.92. The goal is to have a (UV-)Sphere emit smoke and fire in the shape of a cone. After researching, I followed the official docs and added some nodes based on this question. I checked if the domain is actually a domain object and if the flow is actually a flow object and both of them are.
The problem I'm facing is that the smoke and the fire go in the wrong direction (at least from what I can observe). Rotating either cone or ball does nothing, the smoke just moves on an almost two-dimensional plane.
Please download my .blend file since I can't upload images yet because I don't have enough reputation yet.
