rather nasty, my ongoing problem with viewport settings and google search console!
When I have activated in WYSIWYG metatags>automatically include viewport setting, google complains about lettercase that is unreadable: too small. links too close to each other etc. I did solve at firtst with bigger case, but , after a while, got the same message.
however, the site was readable well enough on my phone.
<meta name="viewport" content="width=device-width, initial-scale=1.0">
Than I switched this off in meta tags, and put my own line between heads:
<meta name=”viewport” content=”width=640, height=480, user-scalable=yes, initial-scale=1.0, maximum-scale=5.0, minimum-scale=1.0″ />
</head>
Still, google means, there are no viewport settings at all!
And still, on my phone, the site is ok!
Have some ideas there ??
