HomePod uselss

I have tried everything to re-establish connectivity of my HomePod to my iPad or iPhone. It will play random music but I cannot control what it is playing. Airplay does not work from any device including Mac. All devices are on the same wifi. Basically other than asking Siri a question, the pod is useless to me. I have tried removing the device and re-setting it up. Apple forums instructions to restart the HomePod does not exist in it's menus as the instruction states. At a total loss and to how not just now use this as a paperweight (if I used paper)?
