WizmagePlus uses artificial intelligence to only mask people in images.
Ensure that both the application (from 'Download WizmagePlus' above) and
this Chrome extension are installed.
One without the other won't work.
(The application installer will install the Chrome extension automatically, but it may fail in certain cases.)
If you are unsure if the application is installed, check in Windows Settings -> Apps -> Installed Apps. Or simply install again.
