I have tried every instruction for resetting the Homepod but it is still on my Home app and still not responding. Please help me reset it.

If HomePod isn’t responding, first try to restart it with the Home app. 

Open the Home App - go to the Room it’s in 

Long press on the HomePod icon to bring up settings, scroll down to the gear icon, tap that, scroll to the bottom to Reset HomePod - then select Restart HomePod 

If HomePod still doesn't respond, choose Remove accessory, then set it up again

Reset HomePod

If you can't reset it, delete it and re-install from scratch using iPad with Bluetooth on. There's a new update & I had to do it the other night after my network rebooted.
