Can't rotate guidelines too (ver, 2.3.1)

hi there.
Im using Glyphs 2.3.1 now, but I found a problem.
i’m struggling with rotating the guideline while dragging it.
After updating, I can’t rotate guidlines.

Actually i read on the post having the same problem. but not solved yet.

if you don’t mind, could you check this?

It should be fixed in the upcoming version. As a workaround unit the update is available, you can rotate in the gray info box (Cmd-Shift-I) when the guideline is selected.
