Hi Sebastien! I'm also just starting with APEX, but it appears to me that for your "ik1" and "ik2" autorig nodes, on the "Driven" tab, needs to have "_l" in each of the root, mid, and tip parameters.
So it becomes:
ik1: "hip_l", "knee_l", "ankle_l"
ik2: "scapula_l", "elbow_l", "palm_l"

Remember to set unique names for the polevector and ikhandle in the "Controls" tab so front and back legs have individual controls

Now you might see one of the annoying issues I've run into with IK. It doesn't seem to like mirrored skeletons with negative scaled transforms. It might be worth it to add new drivers to your driven tips maybe with the transformdrivers Autorig Component.

I'm still new to all this, so plenty of grains of salt. But I hope it helps you.

That's awesome! I'm excited to see how it looks, tomorrow!

Thank you so much!

And thanks for the tip about not needing to set the transforms too
