TP-Link Utility for Windows 10 stopped working

Same problem with me, I have installed the new power line utility but it does not find any powerline devices.
With this utility not working, these things are not possible anymore:
Firmware upgrade (or downgrade)
QOS settings on powerline adapters
verify powerline speed between adapters
Although, I today installed a version published on 2020-11-27 of the powerline utility found on the global website on a computer where it never was installed before
It asked me to install the WinPcap 4.1.3 as an additional tool (from Riverbed Technology, Inc) and after I started the tpPLC utility, it did not find any powerline adapter but a few seconds later, they were found and I was prompted by Windows 10 Defender Firewall to allow the tpPLC Utility to communicate with my network.
It looks like this works indeed. So if you struggle with the utility, kill everything that came with the old version, download the new version and see if this also works for you. I verfied my findings on my 2nd computer that could not see any PLC devices by updating the tpPLC utility, so I deleted the utility and removed the cap program from another vendor (maybe this is all you need to do?), did a new installation, let it install WinPcap 4.1.3 and voilà, it also works now on the 2nd computer of mine :).
I did not change the date on my computer, I simply downloaded their official version I found on the global website, this is the version that worked for me:

Hi, I have the tpPLC utility working today on Win 10 but don't know how to interpret the result. 
Can anyone tell me what it means please?
This is the latest 11/2020 version utility using Win10Pcap-v10.2-5002
When I look in my smart phone wifi settings, should I be able to identify the tp-powerline adapter or will I just see the router?
