Has anyone managed to get dlink 8600lh to work with alexa and echo show

[p.tyers@bigpond.com]

dlink app installed and working
Mydlink smart skill enabled and working
Alexa recognises camera device I have called backdoor
Alexa announces when camera recognises movement
BUT when I say "alexa show backdoor" echo show displays "Waiting for mydlink"  and times out after about 20 seconds. I expect to see video from camera displayed as occurs when I say similar command regarding my TP-LINK CAMERA.

Has anyone successfully managed to get dlink 8600lh, or similar dlink camera, working with alexa?
