Hello!
I recently started working with Spine, I have been loving it so far.
My problem is that I can't find the flip X,Y keys checkbox, as shown in the
Spine User Guide-

Yes I am in the Animate mode not the Setup.
Keying the scale from 1 to -1 does flip the attachment but it gives the tween, even though the key is placed right on the very next frame.

What is the workaround for this? Am I missing something? Enlighten me please :notme:
Best,
Nagesh
