I am not sure if this is the issue, but I have had trouble stretching (more in 24 than in other versions).
But it stems from the coordinate 'deltas' being turned off.
I am not sure why I am noticing this more in 24 than in previous versions.
Make sure the deltas are on (relative).
Otherwise all stretching occurs from the project/user origin.
The other thing to watch when working in 3D is if you have the 'surface snap' on or off.
