you should be able to see the device name. andriod phone will be random name, Apple phone should show username. as the name collection takes time, you just have to wait a few minutes for name to appear.
hmm, I would check is your PC connected to router with WIFi or ethernet port?
your PC connect to router can only see the device that connect via same method. (ethernet cable and WIFI are two DIFFerent interface, despite they are from same router).
I think when you paid you were not login in ? in that case, if you logout google sign, you should be able to use Pro. let me know if that is the case for you.
