@visodywp Version 1.0.4 of the plugin does let me enter a value of “0” for either of the “Initial camera position” fields and get the expected behavior.
Thank you!
@soskip I had the same issue.
It looks like the script events are looking for the CSS class for the wrapping container in order to attach them. The buttons don’t do anything because the default class name is .woocommerce-product-gallery and this does not exist in your page.
Configure the “Gallery selector” field under the Appearance options -> Advanced section of the plugin settings. Once you do that, the Fullscreen button should actually work as expected.
