I got an error notice from Google that a site is not mobile friendly because a certain image wasn't found. It listed a bogus name like this: example.com/images-store/?C=N;O=D
I checked the server and there is no image with that name.
I ran the site through checkbot and the relevant page has no missing images
I also checked the page that image would have been on with the google friendly tester and it is mobile friendly.
Is this another bogus warning from Google, or.....?
