Ok, no responses. Guess I must be the only one that does not want to pay $50 a month for non-compliance.
This is what I did to get a passing scan:
Downloaded the jquery 3.4.1 min & non-min
Downloaded the jquery migrate 3.1.0 min & non-min
Put those 4 files in the appropriate jquery folders.
In Visual Studio, searched for all references to jquery-3.3.1 and changed to jquery-3.4.1
Searched for all references to jquery-migrate and changed to 3.1.0
I did a relatively brief test of my site including the nopTemplates themes and plugins and everything seemed to work ok. It was not a deep nor thorough test but all seemed well in Edge console. I could see where jquery migrate was lighting up the screen, but no errors.
I submitted my site for another pci scan and it passed-- no problem. Adios paying $50.
Your mileage may vary.
