I had the same thing happen to me, when I upgraded from V2 to V3 my routines would no longer work. I've gone through all of the steps mentioned here and they still do not work. I even went through and deleted and re-linked everything for Echo connectivity in the ISY portal. Still doesn't work. When I ask Alexa to turn on whatever scene, program, or state variable directly it works. But when I create a routine with that same scene, program, or state variable, it doesn't work.
