Google Optimize not working on all the selected pages
Hello. I've set up the test to run on all the product pages of my website. (The rule is an URL rule that matches every product). The test consists in showing some HTML after a button, which is correctly selected with a CSS selector that is contained in all the product pages (the "Buy" button).
When I check with the preview tool of Google Optimize, I see that HTML content correctly in every product page. However, when I run the experiment, I only see it in some of my products. Is this a bug or am I doing something wrong?
