We value all our customers equally; hobbyists, makers, students, educationalists, industrial and commercial. We are also equally unhappy and frustrated that, whatever Google have changed, is preventing our code which used to work with Chrome-based browsers from doing so, whether that's using PC, Chromebooks or anything else.
We are well aware that Google's change has screwed teachers and their students, especially those using Chromebooks. It was Google which did that. It was Google which screwed those students and teachers, not us.
There is nothing wrong with our code; it worked with Chrome and it still works with Firefox and other browsers. It is plain and simply something Google has changed which is what has stopped it working how it used to, how it is meant to.
We would like to find a resolution as much as anyone else. It is unfortunate and regrettable that we have not been able to do so, that Google's change is causing knock-on consequences for students, teachers and others.
Imagine if your parents had told you; to get an orange iced lolly you should ask the ice cream vendor "Please can I have an orange iced lolly". That works for years. Then one day the ice cream vendor you have regularly used just stares back at you blankly. It used to work, other ice cream vendors still comply with what's asked, just this one and those in the same franchise no longer do.
How are your parents expected to come up with a solution to that ?
The problem isn't with what your parents told you, what you are doing. It worked, still does work with other vendors, it's just this vendor and those in the franchise ignoring what you ask for.
