I have just discovered what the problem is, COMPLETELY by accident!
The scan and KSN reputation check work JUST FINE, but NOT from Windows 11's crappy new context menu that shows up on the first right click (if you click these, nothing happens):
However, if you press "show more options" to show Windows' classic context menu, it works from there:
How absolutely stupid is that?
Why does Windows 11 need 2 completely different context menus, again? Completely stupid design...
Maybe you guys can file that as a minor bug report, I guess.
As for the Android Play store problem, I see that I can update the apps just fine from the Samsung Store.
You have reminded me why I have stuck with this company for the past 2 decades, the support and reliability has always been excellent from Kaspersky. I think that what the US is doing to you guys is completely disgusting, unfair, wrong and unethical. I will always support you.
