Google has been showing errors of “Text too small to read” for the Aqua theme. This happened because some images contain text and information which looks perfectly fine on a desktop. When the aqua theme is viewed on a mobile device, the image resizes automatically making it smaller.

Some other themes overcome this issue by allowing the user to pinch and zoom in on their mobile device in order to enlarge text and images on their phone.

Can something like this be performed on Aqua as well? Currently, everything is LOCKED when a webpage is viewed. Pinching or spreading fingers do not enlarge the images or text.

You can experiment with your viewport meta tag in your header.php template.
By default it looks like this:
<meta name="viewport" content="width=device-width, initial-scale=1, maximum-scale=1">

You can replace it with this for example:
<meta name="viewport" content="width=device-width, initial-scale=1">

or this for example:

<meta name="viewport" content="width=device-width, initial-scale=1, maximum-scale=6.0, minimum-scale=1, user-scalable=yes"/>

Let me know which works.
