Linking to specific page in PDFs

I am trying to link to a specific page within a PDF.

For desktop the URL works with:

https://www.examsolutions.net/papers/edexcel/gcse/nov17/paper2/paper2QUE.pdf#page=3

It takes you to page three, but does not work on mobile. However if I use jQuery

if ($(window).width() < 600) {
   $("a").each(function(){
      var newUrl = $(this).attr('href').replace('page=', 'page');
      $(this).attr('href', newUrl);
    });
}

The URL is changed to:

https://www.examsolutions.net/papers/edexcel/gcse/nov17/paper2/paper2QUE.pdf#page3

The removal of the '=' works, but only on iOS from my testing. Is there a solution for Android or is it not possible due to Adobe PDF licensing etc?

There are thousands of links to exam questions to help students so creating individual PDFs is not really an option!
