Just Flight Arrow trim in MSFS2020

I downloaded and installed the latest version for 2020 a few weeks ago (v0.6.3) because I read somewhere that one of the things they fixed was the trim step. I.e. there was no more "runaway" elevator trim if you used the control for more than a second or two. But as far as I can tell, that's still not working right on the Arrow or Turbo Arrow. Has anyone got that working, or did I misread what the latest changes were?

I say "fixed" because I understood that the issue was originally native to all kinds of planes in MSFS, until Asobo corrected that. But it was still a factor in some GA planes like the Arrow.
