Even though we got the red "X" to become a green check mark, we could not get the iPad to recognize Companion was running on the PC. Once I went off the "public" WiFi and onto our secure internal WiFi, I am able to log on and my iPad finds my PC. Clearly this is an issue with how the public WiFi is operating. Since I have no control over this (or any opportunity to give feedback) I will not be pursuing this.
Josh: Thank you VERY MUCH for your time and attention to this issue for me.
