Migrating an existing page into Hubspot. I have copied the HTML over from the pagesource and am really having no issues editing the HTML to work within Hubspot. I am noticing something with the viewport meta tag. It says its configured correctly, but when I view on mobile it still is pinch to zoom format. When I look at the HTML inside the design tool I can only see the viewport on output, but seem to be unable to edit it. When I want to put the desired meta in, I get dinged for having 2 viewport meta tags.
Try replacing your meta viewport with the following code. The code you have seems overly complex and below is what I have seen to be the most common usage. Basically this tells the browsers to not scale the page.
