I am using the minimal theme and have no issues with the desktop version, however the mobile version opens new windows when you click on product thumbnails. Anyone have similar issues?
Jesse from Shopify here.
When I view your site on my android mobile running Chrome I can tap on the thumbnails and the main product image updates accordingly.
I would first try resetting your browser and clearing your cache and testing again. If you still encounter the problem I would recommend following up here or through one of our live support channels with as much info about the device and browser you are using as possible so we can dig in further.
Feel free to reach out at any time if you have any other questions.
