The server now needs to respond with the Accept-CH header specifying it wants the client to send the mobile client header by including the "UA-Mobile" value. A compliant client will then send the Sec-CH-UA-Mobile header in its next request with either the value "?0" or "?1".

Not supported on iOS, which is a good chunk of the mobile traffic you’re trying to identify.

You have to do a split approach. Last I knew only Chrome-based browsers support the new UA headers. Firefox and Safari only support the User-Agent header which you have to check for the presence of "Mobi".
