You mean by this tag?

<meta name="viewport" content="width=device-width, initial-scale=1, maximum-scale=1">

I imagine the only problem here is the maximum-scale parameter. Is that so, or are there other ones?

I haven't touched a frontend for a few years. It was the case that this tag was needed to display anything on mobile (and Google would all but delist you if you omitted it or used it incorrectly). I imagine things have improved. The optimist in me would like to think that the tag isn't even necessary anymore, but I can't trust that guy.

Yeah, I use this one:

    <meta name="viewport" content="width=device-width, initial-scale=1">

and "initial-scale" is only needed by Chrome Android AFAIK.
