RF 100-500 tripod ring won't tighten sufficiently

I have recently purchased an RF 100-500 lens and am very happy with its performance so far.  However, the tripod ring does not seem to tighten sufficiently to prevent the lens/camera from rotating.  Any advice/solution would be greatly appreciated.
