I am working on a site that has a meta viewport tag with an initial-scale value of 0.8. The full tag is here:
<meta name="viewport" content="width=device-width,initial-scale=0.8,maximum-scale=5.0">
I cannot get Pagespeed insights to recognise this tag – I’m given the error “Does not have a tag with width or initial-scale“. Pagespeed does, however, recognise the existence of this tag if I set initial-scale=1. I’ve tried reordering the parameters.
I can’t find anywhere that states a value less than 1 is problematic, least of all in Google’s Pagespeed documentation which states that the tag merely has to exist in order to be picked up.
Changing the value to 1 has the unfortunate effect of making the site appear jumbo size on mobile devices and breaks the layout.
What am I doing wrong? Have I misunderstood something about how this tag is supposed to work?
Thank you.
