Gearbox adaptive programme or the engine warm up cycle are two most obvious reasons. Mine has improved shifting after updating to nov18 software.

Could also be the fuel. Mine runs noticeably smoother on BP Ultimate, followed by standard BP or shell and the worst is Shell V Power. Those are the only ones I tried. But also you can get bad quality fuel from a petrol pump that has too many contaminants or stale fuel.
