In product page the Zoomed Image will display when I click on the product image. If I click the Close Icon on zoom it displays a blank page sometimes. I expect the zoom window should close. I don't know why it is coming like this.
I think this problem coming in default theme also.
Kindly help me out.
The default theme doesn't have this problem in Chrome, Edge or Firefox. Which browser are you using? Are you using the default Magento product zoom or a Magento image lightbox extension e.g. Magic Thumb?
Please also share a live URL where this behaviour can be replicated.
