Web page not redirected to AMP after accessing page with ?noamp=mobile

Dear admins,

I have a problem about the AMP plugin didn’t redirect the page back to amp after accessing page with ?noamp=mobile with the url.

My website is a hybrid combination of AMP and non-AMP
I’m using the transitional setting and using the is_amp_endpoint() function to make my theme template AMP compatible. I also using the amp_to_amp_linking_element_excluded to exclude my non-AMP pages so the link to the page will be non-AMP (contain ?noamp=mobile)

and I found the example to use the function from a website like this

add_filter( 'amp_to_amp_linking_element_excluded', function ( $excluded, $url ) {
  if ( 
    false !== strpos( $url, '/about' ) ||
    false !== strpos( $url, '/web-design-development' ) ||
    false !== strpos( $url, '/mobile-apps-development' ) ||
    false !== strpos( $url, '/online-marketing' ) ||
    false !== strpos( $url, '/graphic-design' ) ||
    false !== strpos( $url, '/branding-game-development' ) ||
    false !== strpos( $url, '/career' ) ||
    false !== strpos( $url, '/csr' ) ||
    false !== strpos( $url, '/contact' )
  ) {
    $excluded = true;
  }
  return $excluded;
}, 10, 2 );

the code work perfectly and the listed page didn’t redirect to the AMP version.
But if I go to the AMP page (e.g. Home) from a non-AMP page, it will go to the non-AMP page. The page didn’t have ?amp=1 or ?noamp=mobile on the URL.

I’ve tried searching in the forum and google but I can’t find any simmilar problem.

Thank you for the time and help

Best regards
