How to remove ridges from mesh? There seems to be some ridges protruding from the corners that I beveled when subdividing. The beveled edge is at an angle so I not sure if that's the problem with the mesh.I know this is a simple fix but my skills is still very primitive.

After adding loop cuts ridges are still visible
I Insetting the top and bottom surfaces as a whole
CtrlR Putting holding loops into the thin sides
K with C and Z Orthogonally cutting an extra loop through the piece,  back from the curved end


probably does enough, here, depending on how much you want to keep the flat slopes on the profile, etc.
