I can not seem to get sorted with the companion app.
I am running my laptop and my phone on the same network but they are not getting it together.

Sounds like you’re doing the most important thing correctly - putting the smartphone and the laptop on the same WiFi signal.
Are you using a VPN on either of those devices? If so - please turn that off, as the VPN will cause one of them to be invisible to the other. Same thing if either device is using a software firewall.
