Blender 2.8 - Inverse Kinematics Bone Constraints - IK Quick Tips

Do not apply constraints from "Bone Constraint Properties" or "Object Constraint Properties". Apply IK bone constraints in Pose Mode and from "Bone Properties" (the bone icon), go to "Inverse Kinematics" (this option appears in pose mode only)...there you will find the bone constraint options and everything will work as expected.
