When I tap any product image in mobile phone to view it in full screen, Close button appears in top right hand corner. When I try to tap Close button to close the preview, nothing happens. I have to tap back button to close the preview.
Works fine for me. What version of Magento and what device? Does the same problem happen on desktop when you simulate a mobile device?
Magento Version: 2.2.2
Theme: HiddenTechies BizKick
Device: Iphone 5S
Browser: Chrome 64.0.3282.137
I have made these changes to products page:-
(i) added two text blocks (ii) added Facebook Like & Share button (iii) Changed catalog_product_view.xml file to remove Reviews Tab and related text.
I did not simulate a mobile device on desktop, I have tested it on several mobile phones.
I am not able to found browser developer tools in my chrome browser.
