Yes, your demo galleries are zooming correctly in my system (v42/4s/8.3).
Thank you for checking.
I meant the pinch zooming, not scaling.
Thank you for clarifying. So the problem is with pinch-zooming, not the initial scale when the gallery is displayed.
Maybe the following will make sense.
In both your galleries, you use expandInNewPage="FALSE" (rather than the default value of AUTO) which will force the galleries to be expanded on top of their respective embedding pages.
In the Expand Gallery Behavior support section, the following is noted. (It refers to the default setting of expandInNewPage="AUTO".)
To avoid opening in a new page on iOS, the solution is to lock the viewport of the embedding page. This will prevent user scaling of the page via pinch gestures. Juicebox will detect that the viewport is locked and expand in the same page.
On iOS devices, when you explicitly set expandInNewPage="FALSE", Juicebox internally locks the viewport (like it is recommended to do manually if setting expandInNewPage="AUTO" and wanting the gallery to expand on top of the embedding page) to ensure that the expanded gallery fills the browser window correctly (so I am surprised that you can pinch-zoom in Mobile Safari, not that you can't pinch-zoom in Chrome).
The only way to ensure that you can pinch-zoom in both Chrome and Mobile Safari would be to set expandInNewPage to either 'TRUE' or 'AUTO' (to let Juicebox decide how to expand the gallery) and then set your own meta 'viewport' tag in your embedding page (to set the initial scale of the page) if required.
You previously noted:
Now the thing is if I set expandInNewPage= to AUTO or TRUE the page becomes non responsive.
Are you referring to the initial scale of the page when you say this?
Perhaps you could try this again, setting expandInNewPage="AUTO" and using the following tag:
<meta name="viewport" content="width=device-width, initial-scale=1" />
This seems to work fine in my own tests (the initial scale of the page is the same in Chrome and Mobile Safari and it is possible to pinch-zoom in both browsers).
