We have brought up this issue so many times, I personally have brought it up twice for the Live Developers Updates and Seb has actually responded by saying that turbulence is there but he has realized the cloud density is not there to produce the significant amount of turbulence in MSFS 2020! He said it will be fixed (that’s back in Feb. 2024) and it’s two weeks worth of effort. It never got fixed and guess what, it’s not fixed in MSFS 2024 despite all the promises.
Please bring this issue up as many time as you can by submitting this question every time to live developer’s update. Weather should be pretty much the most important aspect a flight simulator. Hope they address this issue sooner than later.
